One approach is to use a cell array and have the entry be a string. E.g.,

a = cell(1,2);
a{1,2} = '10:23:34';

And another is to use the fractional portion of a datenum representation--

>> a{1,2}=datenum('10:23:34',upper('hh:mm:ss'))-
fix(datenum('10:23:34',upper('hh:mm:ss')))
a =
[]    [0.4330]
>> datestr(a{1,2},'HH:MM:SS')
ans =
10:23:34
>>

MATLAB talking to MATLAB?
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.

Run Matlab ... from Matlab
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 .

How to transfer a VC matrix to matlab workspace and manipulate it under matlab GUI ?
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. I tried engdemo.c, but i found that under this mode, matlab runs on background, there is no matlab main program GUI, I can only excute matlab command on C, and see result, like ploting. how should this be done ?

Matlab plots outside Matlab
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.

Calling Compiled MATLAB from MATLAB
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.

Calling Matlab in C in Matlab
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.

Starting another matlab instance from matlab itself
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.

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.
