Multi peak fitting Error -20041

I programmed a multipeak gaussian fit. Its displaying the following error
"Error -20041 occurred at NI_Gmath.lvlib:Nonlinear Curve Fit LM.vi:6620001"
Possible reason(s):
Analysis: The system of equations cannot be solved because the input matrix is singular.
Can someone help me on this?

I cleaned things up a little bit and it all seems to work OK. (might need to tune the peak detector). LabVIEW 2013.

Try specifying an initial guess. I used:

Nonlinear Curve Fit Error

I am trying to get a multi-dimensional fit working by using a nonlinear curve fit VI and everytime I run it I get an error saying that my samples need to be greater than 0. The specific error message is: "Error: Analysis samples need to be > 0." Does anyone know what is wrong? I have tried to reinitialize my input parameter array to zero, recompile the VI, etc. and still get the same error regardless.
I have attach all my VI's.
Thanks,

I am farely new to labview and have not figure out the best way, so that my diagrams stay smaller since my width and height are farely large. What do you mean eliminate the local variables in the loops of the model?
In the model, you have a hidden indicator called pixel size, which you write once outside the loop and then continuously read over and over again with every iteration of the loops via local variables. SInce the value does not change during the execution of the loops, reading the same indicator over and over is just a waste of efforts. Why involve the UI if the valie is right there in the wire?? The correct way would be to delete that indicator and the local variables and simply connect all by wires.
Did you understand my other comments?

Are all of those fitting parameters or are some of them constant and known?

Gaussian Peak Fit and Nonlinear Curve Fit on small data differ from Origin Peak fit

Hi all,
I am developing a program in which I have to fit Gaussian curve on only 4 or 5 data points. When I am using Gaussian Peak Fit or Nonlinear Curve fit, it linearly connects all the points while other fitting software like Origin is fitting Gaussian curve on the same set of data I have attached two images One is from Labview with Gaussian Peak Fit and NonLinear Fit and other is from Origin.
Data is
X                       Y

That looks like a plot of the input data.
When I run it with your data I get a Gaussian curve which looks much like your Origin plot.
The Plot 2 curve is from 128 points equally spaced along X and Y calculated from the Gaussian formula in the LV help using the output parameters from the fit. Plot 1 is the Best Gaussian Fit output from the fit VI. It only has five points.
I used default values for everything except X and Y.

Help needed, can no longer insert Battery3 as a Multi, Core Audio Error.

Hi all,
Well I have been using a few different Motu interfaces as of late, the Ultralite, Traveler and now the 828 MK2. Each device has had no troubles with hBattery as a muti untill now the 828.
I have loaded all sorts of other mutli devices but for some reason battery is a no go, I get a core audio error of -1 ?
Now I have yet to install a different driver set since it was my understanding all Motu drivers are the same and the Audio interface driver page shows the 828 so I figured all was well.
Any one have any ideas as to what I can do? This one has me stumped.
Thanks in advance!

I have the exact same issue, battery 3 won't load as a multi. it's authorized and works as a stereo audio unit, but when i try to load the multi, i also get error code -1. btw, this happened today - yesterday the multi worked. i already trashed the logic and battery prefs, no go.

Multi-thread failure - Error in assignment

Hello
I have a c++ program processor running under Windows XP with Oracle 9i. My program access to oracle by an ODBC driver version 9.2.0.4.0. It could be launched in multi-thread to increase performance. When I launch it with one thread everything is fine. When I use several threads I have problems. ODBC driver returns to me a "error in assignment ... General error" message and my updates queries failed. Under SQl server it works without problems. It seems to be a kind of deadlock. When I disable check box in my odbc driver of "enable query timeout" my program encounter a problem and freezes...
Could someone help me ?

I have thought of the above solutions as workable, however, it is not. Some exhibited errors are:

B. "Attempt to read / write database while database is closed." This error applies to 3 in particular;
C. "Attempt to close environment while some database is still open." This error applies to 5.
Please help me with designing a better strategy to solve the concurrent issue. Many thanks in advance.All these are expected errors. You should design the application so that you do not close an environment handle while database handles are still open, keep database handles open for as long as operations need to be performed on the underlying databases, open the database handles after opening the database handles, and close database handles before closing the environment handle.
In short, in pseudo-code, you should have something like this:
- open environment handle,
- open database handles,
- perform whatever operations are needed on the databases,
- close database handles,
- close environment handle.
You can refer to the Getting Started with Data Storage and the Getting Started with Transaction Processing guides appropriate for the API you are using, from the Berkeley DB documentation page.

Problem with Using Smart Fit - 'Error' mess

When I try to transfer higher bitrate?tracks to my device (MuVo N200)? using the Smart Fit feature, I get an error message: "unable to transfer". This just started happening tonight. I would like to solve this problem as I wish to put all tracks on my device @ 28 so that I can have the maximum amount of music. If anyone has had this problem and knows how to solve it, please reply. Thanx.

Yeah, that seems to work for now. I don't have time to experiment at the moment, but can you do this for several cuts at once and not just for one at a time? I'm sure you probably can. Another question...is there an easy way to convert RealAudio files to mp3 or wma files so that they can either be put on a device, burned to a disc, or just stored in a more convenient format?I know it's a different topic, but your replies were so knowledgable that I was sure you'd have the answer to this as well!?Thanx ,000,000 PeeBee!

Tabular form - Multi row delete error

Apex 4.0.2
We have a simple CRUD type of application on a bunch of tables built using Apex v1.6 that has, over the years, been upgraded to v4.0.2 and it is working mostly fine. It uses all out-of-the-box standard components, forms, classic reports, nothing too fancy. Recently one of the tabular forms started to misbehave, the multi-row-delete process raises a No Data Found error. The tabular form is based on a view with a INSTEAD OF trigger to handle the DML. Manually deleting the row in SQL*Plus works fine delete from mytab here pk_id = :pk_id but selecting the same row in Apex and clicking Delete raises the error.
How does one go about troubleshooting & fixing this sort of thing? I tried re-saving the region in the Builder, exporting/importing the entire app, nothing. Running in Debug mode doesn't really provide any additional information, just that the MRD process failed. Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot.
Any ideas?

Hello Vikas,
>> How does one go about troubleshooting & fixing this sort of thing?
By given us a bit more information :)
• Is it a manual Tabular Form (using the ITEM API) or a wizard created one?
• Are the Insert/Update operations work correctly? If not, what is the type of your PK column(s)?
• If the problem is limited to the Delete operation, maybe the problem lies with the checkbox column. Are you sure that on page it is rendered as the f01 column?
• As triggers are involved, can you save the PK that the trigger sees? Is it the expected value?
• Are there any other processes that are fired before the DML process? If so, maybe the problem is with them. You can temporarily disable them and see if it change anything.
>> Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot
Yes, I agree. However, I believe that 4.1 made some serious advancement where Tabular Form is concerned. Having simplified Tabular Form related Validations and Process should make things easier, and as a result, prone to less errors. Still, the main problem is that the type of error you are talking about is usually the result of metadata problems and these are indeed very hard to track.

Arie.

Multi-threaded error handling method

I have a multi-threaded application. When an error occurs in any of the threads which causes the system to fail, all of the threads throw an error and display an error dialog box. I am thinking about removing the call to the error handler in the secondary threads and instead send the error to the main thread for disposition. Is that a common design pattern? Is there a better way to do this?

Not as common as it SHOULD be.
We use an Event Logger that passes all errors to a background process that logs them to file for review later. That is the minimum. If the errors a fatal then we adjust the app design to react accordingly when bad things happen.

Found Dead Multi-Threaded Server Error!!!

I am in the process of testing an application based on EJBs deployed on an Oracle 8.1.5 database.
Some times the whole instance chashes without any obvious reason.
The error reported in the Alert file is
"found dead multi-threaded server 'SOOO',pid(8,1). Terminating Instance".
I check my code and i think that there is no problem with cleaning up resources. I increased also the JAVA_POOL_SIZE and LARGE_POOL_SIZE size without any result.
Can anybody give me a hint for the error cause?
Thanks in advance.

Multiple Gaussian Peak Fit for Wavelength Spectrum

Hello.....
First, let me confess to being a relative noob..... So please be gentle.
I am trying to create a vi to analyse an optical spectrum of the form: Intensity vs. Wavelength. This vi would need to do the following:
1: Read the input data file.
2: Set a noise floor, below which all data will be ignored.
3: Scan the spectrum and identify the amplitude, width, and center of any peaks that are above the noise floor. There will be multiple peaks present (as many as thirty or so).
5: Fit a gaussian to each peak.
6: Sum the gaussians and create a new data file from this sum.
So..... I know what I want to do, just not the best way to do it. Is there a vi already in labview that will do this for me? The Gaussian fit vi seems only really useful if you want to fit a curve to a single peak. If I need to build this from the ground up, which is fine since I need the practice anyway, what would be the best way to start?
Thanks in advance for any help.

Hello Nia,
There are many ways to approach this problem. By chance, do you have access to the sound and vibration toolkit for labVIEW (http://sine.ni.com/nips/cds/view/p/lang/en/nid/209056)? That toolkit will make performing the signal processing tools which will make creating this VI much easier. The following links may also be helpful for getting started with your issue

We are experiencing exactly the same problem.
Did you get a solution?

MIRO, multi-account assignment, error message M8063,

When I do MIRO referring to a PO with multi-account assignment and Indicator GR-Based Invoice Verification is untick, I receive the following error message u201CDocument does not contain any items Message no. M8063 Diagnosis The document contains no posting lines with a value other than zerou201D.
But when I make a good receipt MIGO, so I can post my invoice correctly (MIRO).
The business process is to post a MIRO referring to a PO with multi-account assignment without a GR.
Thanks

the GR-Based Inv. Verif indicator in vendor master record is untick.
however, I can now post ,but before, in MIRO, I have to enter the quantities and the amounts in the multi account assignment dialog box (in MIRO, clic on the buton called Acct Assgt).
so the question now, why doesn t the system default the multi-account assignment from the PO?
thanks
