3d interpolation table

Hi i'm a new user in labview
and i couldn't find any solution for my problem
i need to create a table with :
1- 3D interpolation ( enter with x , y , values and get z)
2- create a function to make the user able to multiselect values in the table , then push bottom of ( increament , dercreament ,...)
Thanks in adavance

(Sorry, posting by phone)
1- search the forum or help for bilinear interpolation.
2- use a table, then use mouse-down events to toggle selection. Change cell background if selected. Use buttons to increment selected cells, etc. Keep numeric array with values and Boolean array to track selection.

Hi!!I want to scale an analogic signal, and I don´t understand very well how interpolated option works in "Scaling and Mapping".

Can anyone explain to me, the option Interpolated, in the function , "Scaling and Mapping?
Thank you!!!!!

When you select Interpolation you then define a table of value pairs; basically the raw data versus actual data.
For example
2 5
4 10
6 20
What the VI then does is if the input signal has a value of 3 the Express VI will linearly interpolate between 5 and 10 and will map your value of 3 to 7.5. Again a value of 5 would then be interpolated and mapped to 15.
Take a look at the attached VI.

How to calculate an interpolation...

Hi Everybody,
Iu2019m struggling with the percentile calculation using simple interpolation.
I have following inputs:
Table:
Day_bucket             1|     2|     3|     4
Responses             10|     20|     50|     20
Cumul_responses     10|     30|     80|     100
Percentile                     0.1|     0.3|     0.8|     1
1. Day_bucket u2013 days from 1 to 100 (dimension)
2. Percentile u2013 percentile distribution u2013 how many % of all responses have been received in a particular day from Day_bucket dimension (measure)
3.Interpolation equation: d=d1 + ((g-g1)*(d2-d1)/(g2-g1))
g - percentile you are looking for (in my case 0.9)
g1 - MAX percentile < 0.90 (in my case 0.8 )
g2 - MIN percentile > 0.90 (in my case 1)
d1 u2013 Day_bucket where percentile is equal to g1 (in my case 3)
d2 u2013 Day_bucket where percentile is equal to g1 (in my case 4)
d u2013 value Iu2019m looking for (in my case 3.5)
Now what I need to do is to get the result of above equation into one field. And my problem is that I not able to calculate g1, g2, d1, d2.
Can anybody help me? Is it actually possible to make such calculation in Business Object?

Hi gonosgon.
I do think this is possible in Web Intelligence. I think you would need to create some variables in order to do what you need. I am not 100% clear on what you need to do, but if you create some variables in your report, for instance, for g, g1, g2, d1, d2, etc. this may allow you to do what you need. These variables can then be built off other variables.
If you have access to your universe, then you can simply create the objects you need with these pre-calculated.
Hope that helps!

How do I code a 2-D look-up table in a DIadem script?

Based on two existing Diadem variables, what is the syntax for doing a
linear interpolation inside a 6 x 5 table to calculate a third value
that is a function of both of the first two variables? This would
be similar to doing a horizontal and a vertical lookup in Excel.

Hi Brad,
Sorry I wasn't more specific. I've copied the entire table
below; I can reference in any manner that would make sense; its entries
are constants. First I'd like to check the value of a Diadem
variable, 'efficiency', to see if it's between 0.2 and 0.7 (the first
row of the table). If it is outside that range, then the new
variable 'bypass' should be set to zero. Then I'd like to check
the Diadem variable "utility" to be within 5 and 50 inclusive (the
first column of the table). If it is outside the range, then
again bypass should equal zero. If efficiency and utility are
both within range, then I'd like to linearly interpolate between the
values of the table (based on efficiency and utility) to calculate
bypass.

Creating Lookup table in Labview 7.1

For a particular input voltage, the output is distance in cm. For example if the the voltage is 6.2mV the output should be 2.5cm, for 6mV the output is 6cm. Whenever an input voltage between any of these values is given, the output should be interpolated and displayed in cm. I would like to maintain a lookup table for this purpose in Labview 7.1. The graph between input and ouput is a linear graph. I would to know how to create a lookup table and configure it in Labview 7.1..

Well since it is still AE Week here is an AE implementation of a LUT
Inititalize it with an array of raw values along with an array of the tranlsated values.
Use the Lookup action to translate raw to tranalsted.
Itr uses the threshold and interpolate VI to do the translation.

Data Interpolation for Automotive Mapping

Hello all,
I have a lookup table (see attached jpeg) for the main duration pulse (fuel injection) of a diesel engine, every data point (in msec) can be match to its respective speed (top row --RPM) and pressure (leftmost row --BMEP in bar). However, I do not have the complete map and thus I'm missing some points. I was told that LabVIEW has some neat data interpolation VIs that can be apply to this specific case, anyone knows one or knows how to tackle this problem?
Thank you!

Well, if you are running on a LabVIEW FPGA then the Linear Interpolation VI may be of interest. In LabVIEW for the PC the Curve Fitting Express VI or the 2D Interpolation.vi found in the NI Example finder can help out.

Hi ,
For all delta and full DTP loads you can get information in table RSICCONT .Check table RSMONICDP this will give you detail information .Here you will get all the information with timestamp and request id .
Hope these tables will serve your purpose .

How do I get an interpolated scalar value from a 2D lookup table z=f(x,y)?

I have a table of numerical values. Rows correspond to discrete values of a parameter, columns to discrete values of a second parameter. I want tin interpolate a scalar value from the table :
Table Z = f(X,Y)
find Zi,j corresponding to specified X and Y values (which may not be the exact discrete valuescorresponding to rows and columns).
So, I want to find Z(1.5, 3) from a table
X 1 2 3
Y
2 10 15 20
4 50 60 70
The results would be Z = 33.75
The LUT routines interpolate an entire table rather than giving a single answer. earlier discussions have posted routines that find the nearest table entry but do not interpolate between entries.
This sounds very simple....
Thanks.

Have a look at the bilinear interpolation examples quoted in the various links of this idea.

How to do interpolation in oracle

Hello All,
I have minutely level data in the table and I wanted to add these minutely level data for every half an hour and store it seperatly
time value
eg: 06-apr-2004 10:01:00 10
06-apr-2004 10:02:00 12
06-apr-2004 10:03:00 14
06-apr-2004 10:04:00 NULL
06-apr-2004 10:05:00 16
06-apr-2004 10:29:00 14
06-apr-2004 10:30:00 20
The Provblem I am having is In between in an half an hour data their might be null values and I have to "INTERPOLATE" these values and populate the missing value. Can any one please suggest me how to do this in oracle

I wonât be addressing your first question (the one with DATEs) because is not really clear what you want (30 minutes windows ??) â¦ the particularities of your data set are also a bit murky.
For the second test case â¦ first some observations:
1. To make the interpolation results deterministic your table T needs to have some sort of method of getting those rows exactly in the order you listed everysingle_time_ !!
2. What should happen if either the first or the last rows in your list have NULL values?
In any case, exactly for the dataset listed, here is a non-pl/sql solution â¦ there may be better sql-only solutions, but thatâs left for you/others to contribute ;o)

Interpolated Data-Connecting Data Points

Does anyone know how to connect data points that are not sequential? For example, if I have a column with 15 cells and data in cells 1, 5, 8, 10, and 15. When I chart that data, I want those points to be connected with a line, rather than plotted as individual points. In Excel, you select interpolated from the main preference menu under charts. I've searched interpolation and have not found anything. I'm wondering if this function is called something different in Numbers?

The first method I posted works well if you don't need the "blank" categories/rows taking up space on your chart. But if you need to see the "blank" categories/rows, I have a table that I think will do a straight-line interpolation for you. I'm not sure it is error free but, if not, it'll be obvious when you chart it. I'm also not sure it was the simplest way to do it but a lot of the complexity was a result of my making it easy to add new rows to the bottom. I tend to brute force things so if someone has a simpler solution, I hope they post it.
Copy the table to your spreadsheet. Copy your data to the X and Y columns and your category labels to Column A. If you only have Y data then the X's must be a numeric series (like what's in the table now). Plot your X-Y (or Y-only) data as one series and the interpolated column as another series. Change the interpolated data points to "none" and change the line color if you want to (which I did not do below).

Setting color table of intensity graph

Hi!
I set the attribute color table of an intensity graph to a rainbow
distribution of the colors, but now I'm not able to change the color
table with the markers in the front panel.
Do you know a solution?
Thanks, Markus

Intensity graphs have two different modes for its color definition.
The first, typical one, is the Color array. It can be set using
either attributes or interactively and lets you define number/color
pairs that create either a smoothly interpolated or a banded color
gradient. The second mode is the color table. This is useful for
bitmaps or for cases where the color table has been custom generated
on the diagram. When using the color table, the Z scale is still
useful for determining which numbers map to the 0-255 range of the
color table. If you set the
Z scale to autoScale, it will find the
min and max of the data and set the Z to show all data mapped through
the color table. If set smaller, some of the values will map to the
first and last out of range colors. If set larger, it will map the
values to a smaller and smaller number of the colors in the color
table.
It sounds like you really want to be using the color array and not
the color table. The intensity graph automatically switches for
you when you write attributes to it, but there is a way to change
it back the the color array using a popup or attribute.

Linear interpolator

i'm trying to design a linear interpolator as cleanly and performant as possible in pl/sql & sql
imagine i have a trade table
id
and a trade_profile table
id
profile_point
value
which i expect for every trade to contain the profile_points 1, 2, 3, 4 & 5, however that's not always the case.
i can't decide whether i should trawl trade by trade using bulk collect, inspecting each profile point to confirm it exists, and if not,
find the points to left and right and interpolate
or
define an uber sql query, possibly with analytic functions that give me all the inserts.
any thoughts would be appreciated.

Typically the solution, if done purely in SQL performs better then the PL/SQL equivalent.
If you can provide the information below you'll most likely get the solution, if not a good starting point.
1. Oracle version (SELECT * FROM V$VERSION)
2. Sample data in the form of CREATE / INSERT statements.
3. Expected output
4. Explanation of expected output (A.K.A. "business logic")
5. Use \ tags for #2 and #3. See FAQ (Link on top right side) for details.

Table Control Alternatives?

I am trying to find another more sophisticated alternative to the LabVIEW Table Control. Any suggestions? I would like to associate some lookup table code with it to output an interpolated value based on inputs. I actually want to create a lookup table control which highlights the section of the table being accessed and things like that. Does this exist? I have already created the equivalent with a VI and a LabVIEW text based table, but the implementation is not as easy as I would like (creating refrences and all that mess). Dropping it into code takes more effort than I'd like. I'd like to have a self contained control to drop in. Any sugesstions would be appreciated.
R6.

hi,
We have the specify the reference field for the field in table control. Otherwise, we get a short dump showing an error conv_to_number.
To avoid this, we need to set the reference field in the properties of the field in table control.
Double click on the field of table control, we get the properties window opened, in it specify the reference field there.
There is an other simple way to avoid this dump. Select the field of the table contorl and in the TEXT inputbox which exists on the top right of the window, set last letter as _______V But in this case, we get the values justified to the right.

Hi All,
i got an error while dropping a table which is
ORA-00600: internal error code, arguments: [kghstack_free1], [kntgmvm: collst], [], [], [], [], [], [], [], [], [], []
i know learnt that -600 error is related to dba. now how to proceed.
thanks and regards,
sri ram.

00600 errors should be raised as service request with Oracle as it implies some internal bug.
You can search oracle support first to see if anyone has had the same class of 00600 error, and then if not (and therefore no patch) raise your issue with Oracle.
