Best Way to do this array manipulation

I have an array as follows:
61 3 51 5 61.2 3.4 51.3 4.3 61 7 51 4
where the data is in sets of two so array[0] and array[1] make up one data set (61,3) and the next data set is (51,5) then (61.2,3.4) ect. What I want to do is to clean this array up so that any data set where the X values are within some set value, say 1 then they are seen as duplicates and removed, unless the y values differ by more than 1. So for example this set would clean up to
61 3 51 5 61 7
Is there any nice way to do this in labview?
Thanks.

I tried to use the following VI but it doesnt seem to work, any suggestions? Thanks.

  • What's the best way for reading this binary file?

    I've written a program that acquires data from a DAQmx card and writes it on a binary file (attached file and picture). The data that I'm acquiring comes from 8 channels, at 2.5MS/s for, at least, 5 seconds. What's the best way of reading this binary file, knowing that:
    -I'll need it also on graphics (only after acquiring)
    -I also need to see these values and use them later in Matlab.
    I've tried the "Array to Spreadsheet String", but LabView goes out of memory (even if I don't use all of the 8 channels, but only 1).

    But my real problem, at least now, is how can I divide the information to get not only one graphic but eight?
    I can read the file, but I get this (with only two channels):
    So what I tried was, using a for loop, saving 250 elements in different arrays and then writing it to the .txt file. But it doesn't come right... I used 250 because that's what I got from the graphic: at each 250 points it plots the other channel.
    Am I missing something here? How should I treat the information coming from the binary file, if not the way I'm doing?
    (attached are the .vi files I'm using to save in the .txt format)
    (EDITED. I just saw that I was dividing my graph's data in 4 just before plotting it... so It isn't 250 but 1000 elements for each channel... Still, the problem has not been solved)

  • Event Structures​-best way to implement this UI?

    I am trying to write a VI to control & read data from 4 different "channels" (each measuring a DUT) at once.  I have written all the VI's for initializing instruments, communicating with the devices (VISA, GPIB), setting bias, reading data, etc...that has all completed. I just need to write the overall program with the user interface to allow the user to control these 4 channels & display the measured data.....as it turns out, this is the tricky part! My head is spinning from trying to figure out how to handle all the possible events.
    Basically for each channel, I want the user to be able to
    -enable/disable it  for measurement (e.g. if  there is no device loaded in Ch.3, we don't want to measure Ch.3..maybe disable/grey everything)
    -set bias conditions (only if channel enabled). Allow user to change bias "in real-time" by increment/decrementing (e.g. incrementing from 5.00 V to 5.01 V, for example).
    -turn biasing on/off (again, only if channel is enabled)
    Also,  I want each channel to display its measured data (e.g current, temperature reading)..every second or so. No graphs or anything fancy (for now! ), just numeric indicator. 
    Honestly, this all sounds so simple but I'm having trouble figuring out the best way to implement this, due to the fact that 1) there are multiple channels needing to be monitored for events  2) large number of user events that could occur (seems like at least 4 per channel - enabling/disabling, turning bias on/off, incrementing/decrementing bias values, etc ), Also the if a channel IS enabled, i want to be continously reading/displaying the data.  What is the best way to handle this? Should i have 4 separate while loops, each with an event structure to handle events for that particular channel..or will that give me grief somewhre? 
    Also, I have another nagging question. Pretty much all the examples I see re: Event Structures and booleans involve latched booleans, eg. buttons that are just pressed once and pop back up...e.g. buttons you press to tell it to complete a task (e.g. "Acquire Data" or "Stop") , and once it's pressed it's over and reset.  In my case, some of the booleans would not be latched...e.g. the "Enable Ch.2" button would be 'TRUE" as long as i want Ch. 2 to be read....does that make sense? Then, say hours later,  if i did want to disable that channel,  i would change it to "FALSE" and while that would be an "value change", the new value would not be "TRUE"..does that make sense? So  not sure if that would be dealt with the same way in an Event Structure. 
    Hope this all makes sense and many thanks in advance for any help!!!

    You're halfway there. I'd say the best solution is a producer/consumer structure, the event structure is used to generate queued commands to the consumer loop.
    All data is handled in the consumer loop, where you among other things have an array of clusters of channel/instrument settings. (I usually have several cluster, one for test data, one for instrument settings, one for general settings and so on)
    The event structure can have a 1 sec timeout, in which you queue up a Measure command.
    In the consumer, in the measure state you loop through your instruments and if enabled you measure them and update their indicators.
    The general (smart) way to setup the queue is with a cluster containing 2 elements, a typedef'd Command and a variant.
    This way you can send data with the command in any form which is then interpreted in the consumer.
    If, e.g. you press the Enable button on a channel, you can enqueue Enable and the channel number.

  • Theory - Best way to store this type of data for retrieval?

    Hi everyone,
    So I'm pretty new to databases and I'm trying to figure out an efficient way to retrieve this kind of data:
    an ID that is 36 digits long
    col1 = {option1, option2, option3...}
    col2 = {option1, option2, option3...}
    coln = {option1, option2, option3...}
    I need to be able to perform queries on the data based on some concatenation of 3 digit sequences for the ID
    for example, I may want to retrieve all the records where the ID begins with '123' or where the ID begins with '123123', or '123123200', etc,
    There are going to be close to a billion if not more of these records
    the 3 digit sequences will always be a number between 000-255
    It is not necessary for me to have a 36 digit long ID, I simply chose that because it seemed like the simplest way to associate a record with its combination of 3 digit sequences.
    Like I said, I'm very new to databases. I've been doing a lot of reading on indexing and clustering and nested tables and partitions, but I'm not quite sure which of these I should pursue with this kind of data. Most of the examples that I've read about don't really deal about querying with variable precision.
    Would the best way to get this data simply be to use an 'is like' statement on the ID? If so, are there any kinds of indexing I should take a look at that would benefit from knowing that the is like statements would follow the format of <3 digits,3 digits,3 digits>? Also, at the data level, would it be more efficient to use hexadecimal to store the sequences of 3 digits since they conviently fall in the range of 00-FF? I'm just throwing ideas out there, I haven't found much help browsing the web, but maybe I haven't looked in the right place. If anyone has any ideas or places to redirect me, it would be great!
    Also, I know sometimes it helps to know the main kind of queries on the data that someone is primarily concerned about. In this case, most queries will be selective counts, for example finding the number of records whose ID's begin with '123006011' and col1='option1'.
    Thanks,
    Alex

    So I'm starting to rewrite my code. I was shocked at how easy it was to implement the SAX parser, but it works great. Now I'm on to doing away with my nasty string arrays.
    Of course, the basic layout of the XML is like this:
    <result1>
    <element1>value</element1>
    <element2>value</element2>
    </result1>
    <result2>
    I thought about storing each element/value in a HashMap for each result. This works great for a single result. But what if I have 1000 results? Do I store 1000 HashMaps in an ArrayList (if that's even possible)? Is there a way to define an array of HashMaps?

    "php 5.3.x + oracle 11g R2 XE 11.2.x.x"
    Hello everyone,
    I'm quite new to oracle (2-4 months) and php(2 weeks).
    I have one query with results that needs to be reused in several parts of my website. I can't seem to find the equivalent of the mysql_data_seek in Oracle. I wanted to reset the cursor/pointer of oci_fetch($result) so that I can scroll the result again.
    So far this are what I have come up:
    A. On first fetch put the the results in a php array and call the array later on.
    B. Do the query again.
    C. Keep on looking for a mysql_data_seek equivalent and fail.
    I'm leaning towards option 'A' but I just wanted to consult the experts.
    Thank you!

  • TS1314 I have lots of organized photos on my PC and I want to keep them organized to sync to ipad.... how is the best way to do this?

    I have spent a lot of time saving, organizing and arranging photos (for the last 7 years) on my PC, and would like to know the best way to transfer these, AND MAINTAIN THE ORGANIZATION OF THE FOLDERS, to my new ipad (and later, my iphone). I have a really good system, and I do not want to have to do it all over again, on the ipad. I DO NOT want to subscribe to another monthly service fee (i.e. the iCloud) but DO have iTunes on my PC.
    What is the simplest method to do this ?  I have tried synching, but, each time have lost photos (on my ipad) OR have had NO ORGANIZATION AT ALL to the photos once synced.  I have all these photos (5.6gb) in the My Pictures folder, then subdivided into years, then subdivided into events and months within the years.  So, my transfer of the My Picures folder, completely transfers all of them, but with NO further organization.  Again, I have spent years doing this, and don't want to have to re-invent the wheel. 
    Can someone advise (or even better, lead me to a youtube video) that accurately shows the best way to do this ?
    Thank you, in advance, for your help.
    p.s.  I particularly enjoy Dan Nations very informative articles on how to get the best from my products.  And, wish Apple would explain "how it works" regarding the syncing methods on the Operating System.  It is the only thing I "don't get" about using my iPad..... meanwhile I LOVE my new mini ! ! ! ! ! ! ! thanks Apple, for keeping things simple.... Please don't change that !

    Correct, it will only be one-level, the Photos app doesn't support sub-albums - the sub-folders photos will be included in the parent's album.
    If you select My Pictures at the top of the Photos tab when syncing, then you should get an album for each folder that is directly under it - so if I understand correctly what you described then that would mean an album for 2013, one for 2012 etc. And each of those should include all the photos in the subfolders under it - so 2013 would include the photos from the events and months subfolders under it.
    You can't sync them separately, only the contents of the last sync remains on the iPad, by not including a folder in the next photo sync you are effectively telling iTunes that you no longer want that folder/album on the iPad so it will be removed and be replaced by the contents of the new sync (you can't delete synced photos directly on the iPad, instead they are deleted by not including them in the next sync).
    The app that I use, Photo Manager Pro, allows you to select and copy a folder (via FTP), but you would need to select each subfolder individually, which if you have a lot would be time-consuming (I think that if you select '2013' it would ignore the folders beneath it).

  • I am trying to make a pdf of a file and I need to get the file size to be no bigger than 10MB. What is the best way to do this

    I am trying to make a pdf of a file and I need to get the file size to be no bigger than 10MB. Even when I save it, the image quality at minimum the file size is 10.9 MB. What is the best way to do this

    @Barbara – What purpose is that PDF for? Print? Web?
    If web purpose, you could convert CMYK images to sRGB. That would reduce the file size as well.
    A final resort to bring down file size is:
    1. Print to PostScript
    2. Distill to PDF
    That would bring file size down even more. About 20%, depending on the images and other contents you are using, compared with the Acrobat Pro method. If you like you could send me a personal message, so we could exchange mail addresses. I could test for you. Just provide the highres PDF without any downsampling and transparency intact. Best provide a PDF/X-4.
    I will place the PDF in InDesign, print to PostScript, distill to PDF.

  • HT1451 I need to move my library from my old computer to my new laptop. What's the best way to do this?

    I need to move my library from my old computer to my new laptop (Windows 8). What's the best way to do this?

    These are two possible approaches that will normally work to move an existing library to a new computer.
    Method 1
    Backup the library with this User Tip.
    Deauthorize the old computer if you no longer want to access protected content on it.
    Restore the backup to your new computer using the same tool used to back it up.
    Keep your backup up-to-date in future.
    Method 2
    Connect the two computers to the same network. Share your <User's Music> folder from the old computer and copy the entire iTunes library folder into the <User's Music> folder on the new one. Again, deauthorize the old computer if no longer required.
    Both methods should give the new computer a working clone of the library that was on the old one. As far as iTunes is concerned this is still the "home" library for your devices so you shouldn't have any issues with iTunes wanting to erase and reload.
    I'd recommend method 1 since it establishes an ongoing backup for your library.
    If you have an iOS device that syncs with contact & calendar data on your computer you should migrate this information too. If that isn't possible create a dummy entry of each type in your new profile and iTunes should offer to merge the existing data from the device into the computer, otherwise the danger is that it will wipe the information from the device.
    If your media folder has been split out from the main iTunes folder you may need to do some preparatory work to make it easier to move. See make a split library portable.
    Should you be in the unfortunate position where you are no longer able to access your original library, or a backup of it, then see Recover your iTunes library from your iPod or iOS device for advice on how to set up your devices with a new library with the maximum preservation of data. If you don't have any Apple devices then see HT2519 - Downloading past purchases from the App Store, iBookstore, and iTunes Store.

    The best way, really the only way, is to purchase Snow Leopard.
    Online (UK): http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
    Elsewhere: call the phone number in the Apple Online Store.
    Apple's price is $19.99, £14.00, €18.
    Snow Leopard is not available to download from any legitimate source.
    Once you install Snow Leopard, upgrade iTunes to version 10.7 or the latest, iTunes 11.
    iTunes 10.6.3 is the last version of iTunes to support Mac computers with Mac OS X 10.5.8 with either Intel or PowerPC processors, but since you have an Intel iMac, the best solution is to purchase Snow Leopard. Leopard is no longer available from Apple and prices from aftermarket vendors can be unreasonably high.

    I don't recommend you send the iMac in a checked bag. Might get damaged.
    Check the airlines website for carry on guidelines.
    Or, if you have the original box that the iMac came in, if you have someone who can pick up the iMac for you, send it ahead Fed Ex and insure the package.
    Just make sure the display is covered to protect it. A blanket perhaps.
