Is matlab's fminsearch implemented in Labview?

We are trying to implement Matlab's "fminsearch" in Labview. Has anyone else tried to do this?
Cheers
stu

Hello,
Introduced in LabVIEW 8.0, MathScript provides a general level of compatability with The MathWorks, Inc. MATLAB® software. You may find the MathScript implementation of the function fminsearch adequate for your needs. To try it, launch MathScript from LabVIEW by going to Tools >> MathScript Window. For additional information about LabVIEW MathScript, check out the MathScript Forum.

How to generate and use Matlab(R2007) .dll's in Labview

Is there a step-by-step example on how to generate and use Matlab(R2007) .dll's in Labview.
Our experimenal hardware is LabView-controlled and we want to pass
images/2d intensity arrays to a more complex matlab program that will
return an array of extracted data which we want to use in LabView again.
Thank you
Carsten

I recommend having a wrapper created around the matlab dll that converts the datatypes for you. There is a lot of fooling around with pointers involved which is very difficult in LabVIEW. btw, this got much more complicated after Matlab 7. Essentially, you need to convert your inputs into mxArrays, and then add those mxArrays to an mxArray list that you pass by pointer into the matlab dll. You also need to create a mxArray list for the outputs from the dll which you will need to extract your data out of before converting it back into a LabVIEW supported datatype. It's a big hassle. We do this pretty often, but we have created a c library that handles all the conversions, so it is feasible for us. Unfortunately, I can't share the library, but hopefully this information will help you get where you want to be.
Like I said, it would be easier if you can just get a c developer to write a wrapper for you to keep it simple in LabVIEW. Alternatively, you might try getting your m-code to work in Mathscript.

Not able to create OUT file with "nidll_vxworks" in Matlab for use with the LabVIEW SIT 2010 and a cRio 9073, sh.exe error

I am trying to compile an OUT file for my Simulink model using "nidll_vxworks" and run it using the Simulation Interface Toolkit for a cRIO 9073 . I am able to compile the DLL file using "nidll" and succesfully run the simulation using my PC as the host.
I already downloaded the "gccdist" and "vxworks61gccdist" folders and copied them to "c:" When I build the model in Sumulink I get the following error at the end of the process (at the same time windows tells me that "sh.exe" has stopped working). If it matters I am running Windows 7 64bits, but using Matlab 2009b 32bits and LabView 2010 32 bits. ANY HELP WILL BE APPRECIATED. "QofV" is the name of my Simulink model and I changed to "XXX" parts of the file path.

I have some software problems of running matlab script node in the LabVIEW program.

Hi there,
I wrote a simple matlab code, like x= 1, y = x*2. Then I tried to put them into matlab script node in LabVIEW.
However, when I ran the program, I couldn't run and Labiew show some error.
Then I tried the method talked before on this forum. Please see the following link.
http://forums.ni.com/ni/board/message?board.id=MathScript&thread.id=571
I followed the instruction and open the "command prompt," type some commands then I could run the program, and simultaneously, the LabVIEW program open "Matlab command line window" and run my labview code. However, if I didn't use the command prompt, the "matlab command window" will not be opened by running the labview program. It would just show some error. And even if I turn on the matlab program in advance, I still couldn't run the labview program.
Is there any effecient way to deal with this problem without using "command prompt?" Because I try another PC with both matlab and labview installed on it, I "can" run my simple matlab script node on it, and it will open the matlab command line window automatically by running my code. Therefore, I thought there might be some software linking problems in the previous PC I used . Do you have any ideas?
Thanks in advacne.

This board is for Mathscript, but you seem to have a matlab problem. You should probably post in the LabVIEW forum instead.

Running matlab program via switch in labview

Hi,
I had a basic question on integrating a matlab m file into labview. What I pretty much want is the ability to run a certain m file at a flip of a switch.
I essentially created a reset button and that reset button will reset my device.
I attached my block diagram to my best guess to how it would work but when I tried to run it, it does not run the m file.
Any reason why? I tried while(y==1) and if(y==1) to run it but doesn't seem to work.
Thanks! Looking forward to hearing from you!
Justin

Just remember to put Wait statements in the loops so they don't run the CPU at top speed.

MATLAB DataPlugin for 64-bit LabVIEW

Where is the 64-bit LabVIEW support for writing Matlab .mat files? Or is the source code available for the 32-bit version (http://zone.ni.com/devzone/cda/epd/p/id/4178) so that someone can compile their own?
Thanks,
D

To clarify what Chris said, 64-Bit Operating Systems with a 32-Bit emulation (x86 directory) are certainly fine with 32-Bit LabVIEW. (this excludes Windows XP 64-Bit as it has no emulation layer)
Most general 32-Bit vs. 64-Bit LabVIEW questions are covered in this KnowledgeBase article.
To summarize, you'll have full LabVIEW functionality with the 32-Bit version.
The 64-Bit version of LabVIEW is really only recommended for Vision applications that need the additional resources for large image processing.
As another note, currently, most of our software also only supports 32-Bit versions of The MathWorks, Inc. Software.

I cannot run the matlab script node in the labview

Hi there,

Hi, and thanks for the post! I hope your well today.
This may help,
MATLAB® version 2006b (7.3) and version 2008a do work with LabVIEW
8.20. This problem can occur if a new version of the MATLAB® software
is installed along with a previous installation, which is then
uninstalled. The uninstallation of the older MATLAB® software results
in removing the ActiveX/COM components LabVIEW uses. This can cause the
MATLAB® script node in LabVIEW to stop working. There are three
solutions to this problem.
Uninstall the MATLAB® software and reinstall it. This should install the necessary ActiveX component.
Restore the MATLAB® automation server. Browse to the \bin directory (e.g. MATLAB\R2006b\bin) and type matlab -regserver ,
which will reset the registry settings and start the server. The server
can then be closed and the MATLAB® script node will work properly again
in LabVIEW. LabVIEW may need to be restarted if VIs are open that
contain MATLAB® script nodes.
Leave both versions of the MATLAB® software installed.

Matlab code much slower in Labview MatlabScript than in Matlab

I was using an algorithm written in Matlab that executed in less than 2 seconds. Now I need to use it within a Labview program and I am using Matlab script with the same algorithm, but it lasts 10 times longer than in Matlab. Is this normal? Thank you!

How do you know that it is 10 times? Did you create a benchmark?
What are the conditions for the benchmark? Can you provide the code for it?
I am asking this because if you create the VI and put the m-script in the script node, and then press run (looking on the watch) and wait for the VI to finish, you "benchmarked" compile times, memory allocation as well as the complete VI's execution (including the script node of course). I doubt that this will ever be comparable to the "benchmark" in MatLab.
If you provide your VI, we might also be able to give some hints to increase performance.

Control implementation in labview

Dear Sir,
I am a novice in Labview. I wish to implement a feedback controller on labview. I dont have a Control Design and simulation module. Can i implement the controller with this module.
The characteristic of controller is like a first order low pass filter.
Could you direct me some examples where control implementation is done on pure labview.
Regards
Sachin

Dear Sachin,
There is nothing that you cannot do with LabVIEW (just to boost your moral ).... Now if you choose not to use any module/toolkit, you need to develop a model using primitive and other library functions available within LabVIEW... And you already know that... Now what I don't know is, what exactly is the issue.
Sachindian wrote:
Its a first order controller. b/(s+a).
Just convert it in TIME DOMAIN and code for that equivalent model.
For you example, I've attached an example, which is equivalent of 'Only P' controller (in context to PID controller).
I am not allergic to Kudos, in fact I love Kudos.

How matlab function is work in labview

hi all
i have implenet a function say
function [op]=myimplement(ip) in Matlab
& i have used it in simulink as Matlab function
as i have attached the both matlab file name & also Simulink file
i want to convert the matlab function int Labview
i have tried by using Matlab script node
but its is not working ??
so where iam doing any mistake??
iam also attaching Labview file as well name funct.vi
waiting for any kind replay

As it is the Matlab node can't really do anything with that. It would be no different than if you have a .m file. You need to call the function. The Matlab node does not do that automatically (and neither does the Matlab editor). Of course, it's probably simpler to just remove the "function" line and have the last line changed to say
uk=[x_ukp1;x_ykp1;x_zkp1;thetakp1(];
instead of
op=[x_ukp1;x_ykp1;x_zkp1;thetakp1(];
Note: I believe your input variable should be "ip", not "n", since you calculate "n" in the script.

Mathscript/Matlab fir1 function vs. LabVIEW FIR coefficient?

I'd like to convert some Matlab/LabVIEW Mathscript function into LabVIEW block functions, because it's faster.
One of the function I'm not sure is the FIR function: I have a Mathscrip function fir1(n,W), is "FIR windowed coefficients" its LabVIEW equivalent? If yes, how should I match the parameters (e.g. is W the high or low curoff frequency? is Order n the same as the number of taps)? If no, which LabVIEW function should I use?
Thanks.

Hi pji,
I don't have LabVIEW, but I found some really useful resources in LabVIEW Help (open labVIEW>>Help>>search the LabVIEW Help>>search)
Search for fir1 and it contains the syntax, paramter definition and some example codes which you can simply copy and paste and run
b = fir1(n, w)
n: Specifies the filter order. n is a nonnegative integer.
n must be even for filters with a non-zero gain at the Nyquist
frequency. If n does not meet this condition, LabVIEW increases
n by 1.
w: Specifies the cutoff frequency of the filter. w is real number
between 0 and 1. 1 represents the Nyquist frequency.LabVIEW Help has abundant information, check it out!!!
