Long story short, here is the criteria I need. 1) I need two modules running in parallel. One function must activate these two They don't need to START at the same time but both neither return info nor end. They run pretty much infinitely 1.1) I would prefer if the One function also ran separate from the above two in it's own loop but i can deal with a 3'rd function also not ending. 2) I need a shared variable between two of the modules. 1 Module will place information there while the other just reads it, but as they are running parallel. That's it. I can do this in pretty much any other language but matlab I've been having issues with. Problem is I absolutely need to use matlab for one module. If this is impossible to accomplish all in matlab then can i instead run this in C and call one matlab module with separate thread? Sample code below. function mainParallelTest() persistent counter; counter = 0; parfor i=0:2 if (i == 0) ImageProccessorParallelTest(); elseif(i == 1) EventProcessorParallelTest(); elseif(i == 2) prevCounter = 0; tempCounter = 1; while(true) tempCounter = counter; if (tempCounter == prevCounter) %disp('hi') end prevCounter = tempCounter; end end end

The primary mechanism for communicating between MATLAB workers executing in parallel is labSend and labReceive - which operate within an SPMD block. It sounds like you might want to do something a little bit like this. In this example, worker 1 sends 'work' to workers 2 and 3, and then gets them to quit by sending them empty 'work'. Workers 2 and 3 just consume work until there's no more. parpool('local', 3); spmd if labindex == 1 for idx = 1:2:100 labSend(idx, 2); % send work to 2 labSend(idx + 1, 3); % send work to 3 end labSend([], 2); % tell 2 to quit labSend([], 3); % tell 3 to quit elseif labindex == 2 || labindex == 3 % here 2 and 3 are responding to 'work' in the same way. done = false; results = {}; while ~done work = labReceive(1); if isempty(work) done = true; else results{end+1} = max(abs(eig(rand(work)))); end end end end Cheers, Edric.

Hi all, I'm going to work on a project involving a parallel version of MATLAB - I'm aware of various efforts like MATLAB-*P and so on Right now I need to read up on some material regarding MATLAB internals eg: How are the ATLAS(or is it BLAS) routines called in MATLAB? How does MATLAB's C code store information in memory, cache'ing etc? How is one to get at those? Do you know of any suitable reference(s)/resource(s)? Thank you very much, Aravind ...

hi. really need help. i've to transmit an image serially between two computers using matlab on both transmitting and receiving ends. i've encoded the image into binary. been facing problems with the transmission when i used the command fprintf. when i executed that, i got a warning saying timeout occurred before terminator was reached. plus the receiving matlab hangs. i was told to save the binary packet into m-files then transmit the file over. how do i do that? is there a command to save and retrieve binary packets into and from m-files? i really need to get this done asap.thank you....

Hello.I'm in desperate need of some help here, I want to import various images of clouds taken about 30 seconds in one another as a single video file the loop I used to originally do this consisted of: files = dir(Directory of files) for i = 1:100 str = strcat('Directory for workspace',files(i).name); clouds(i,:,:,:)=imread(str); end; But the images it produced were 4-d uint 8 and i was unable to read them or work with them at all. Please can you offer me some type of solution. The main goal of these processed cloud images is to be able to track the movement of clouds in the skys so if you have any demos that I could look at please post them On 28/12/10 8:49 PM, Linus Hamann wrote: > Hello.I'm in desperate need of some help here, I want to import various > images of clouds taken about 30 seconds in one another as a single video > file the loop I used to originally do this consisted of: > files = dir(Directory of files) > for i = 1:100 > str = strcat('Directory for workspace',files(i).name); > clouds(i,:,:,:)=imread(str); > end; > > But the images it produced were 4-d uint 8 and i was unable to read them > or work with them at all.

Hi everyone! I hope you can help me with my probem. I want to reduce noise from a speech signal using an FIR Wiener filter. I am using the Wiener- Hopf equation to get the filter parameter, and in this equation, we need to compute autocorrelations ( or power spectrum). But first, I want to window my speech signal using 256 size windows. I only succeded in writing a matlab program that windows my signal in consecutive windows( a 256 window after a 256 window..etc). My problem is that I want the windows to partially overlap: That the second 256n window starts after 100 samples from the beginning...

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, I am a beginner of using matlab. I am now doing a project about cancer detection in matlab. I've got 120 samples which have classified as tumor or normal cells from patients. For each sample, there is 19200 parameters which are gene information of the cell. My objective is to find the best combination of parameters to classify the sample whether it is tumor or normal.
