For my project, I need to have a client program (MATLAB executable) talking to a server program (also MATLAB executable) to query data. Is there any easy way to accomplish that? I appreciate any help that I can get on that. Thanks. Cheers, Hoi Oops, I forgot to mention. There are multiple clients querying the server, so I guess serial objects + remote serial port wouldn't work.

Hello, Is there any limitation to run Matlab from Matlab, as a system command, on Linux platforms ? I tried to start Matlab, both using the ! syntax (!matlab&) or the system command (system('matlab&')), the Matlab splash screen appears, but the new Matlab session closes rapidly . When I do the same with a script of mine (system('matlab -r "myscript"&')), my script is being executed, but Matlab finally crashes . If I remove the &, it works well, but the first Matlab session is blocked till I close the second one . I run Matlab on a Linux 64bits platform .

It appears there is a parsing problem in the script that invokes Matlab. Here's an example of what I had to do to get around it: !matlab -r \""...

I would like to transfer a VC matrix to matlab main program workspace, than i can observe it by Matlab array editor, or directly manipulate it under matlab GUI.

Hello, a)I need to create an M*M matrix of all zeros, except for one row on ones in the center. M in the matrix will vary from 16, 32,64,128. b)I need to repeat the above for two rows of ones.Here the two rows of ones should be seperated by four rows of zeros.

I'm making an end-user application where I would like to use Matlab functionality both for calculation and plotting. Matlabs GUI builder guide does not satisfy my needs (no support for f.ex. internal frames and other nescessities), so I'm planning to compile my Matlab code and use other API (Java, QT or something) for GUI. My problem is then, that I loose access to the neat plotting commands availible under matlab GUI... Is there a way of integrating Matlabs plot functionality into another GUI system? - has it been done? - I appreciate any response! - P�l Berge ...

Hello everyone, How do I compile MATLAB M files into a form that can then be called from within the MATLAB interpreter? A roundabout way would seem to be to (somehow) Turn the matlab code into C (I think mcc does this), then compile this C code into MEX format and call that. Is there an easier way? I have the MATLAB compiler, so I just need to know what to do with it to get this to work.

Hi guys I am now experencing a great difficulty in the interation between java and matlab. I have an objective function written in JAVA with has method return an numerical number, i call it 'profit'. The nature of this obtive function (ObjFun.java) is that it takes an parameter input, say C, with different C value, the returned profit value is different. Eventually I want to find the optimized C value which produce the maximun profit (C will be under constrains). Initially I want to use linprog or fminsearch in matlab. So I tried the command in matlab that excutes my ObjFun.java. But it failed because my ObjFun.java will call an external .exe file. and the file path contains spaces which is fine by Java but not matlab. I stuck here, I myself is a Java programmer not good at matlab, I can't find any thing on google about the solution to my problem. So here I propose another idea: call matlab function in JAVA. I need some advise on this. Thank you very much for a reply!!! Lemon can anyone give advice??

Hi everybody! My problem can be described as follows. I have a tool in Matlab that requires calling an optimisation algorithm in C. This algorithm consists of several C-files, one of which contains the function to be minimised (CFUNCTION), and another is the main algorithm file (CMAIN). Now what I want to do is to call Matlab from CFUNCTION or CMAIN and specify my custom function (MFUNCTION) to be minimised. So, I'm calling Matlab from C from Matlab. I'm a newbie in C and MEX files. Should I rewrite CMAIN as a MEX file and include CFUNCTION in this and then use mxCallMATLAB? Or can...

using MATLAB to to convert time domain data to frequncy tomain in side labview Hello Mans, Could you provide a bit more detail about the problems you are getting with converting time domain data to frequency domain data in LabVIEW. There are many different analysis and transform vi's within LabVIEW which you could use. Depending on what your trying to do, you may need to install the Math Interface Toolkit which allows you to communicate to MATLAB from LabVIEW. I don't know if you currently have this installed but if you don't, please find the link to the page on our website belo...

Hi All, Is it possible to start another matlab session from matlab itself and have both of them running at the same time? My operating system is linux. I have tried to use system('matlab') but it doesn't work very well because the old session is hanging until I exit from the new session. Doing system('matlab&') also does not work, the new session seems to start but apparently is terminated right afterwards. I am running matlab in linux, if that makes any difference.

Hint: Check for a misconfigured environment or installation. When I look in the referenced directory, there does appear to be an ICU related .dat file. Any ideas as to what could be causing this runtime warning? Thanks. ...
