I am trying to to some computations and I would like to do it in parallel using parfor or by Opening the matlabpool.. as the current implementations is too slow: result=zeros(25,16000); for i = 1:length(vector1) % length is 25 for j = 1:length(vector2) % length is 16000 temp1 = vector1(i); temp2 = vector2(j); t1 = load(matfiles1(temp1).name) %load image1 from matfile1 t2 = load(matfiles2(temp2).name) % load image2 from matfile2 result(i,j)=t1.*t2 end end It work fine but I would really like to know if there is a way to speed thing up ... Thanks a lot in advance! ...

Hello, I'm evaluating products for writing my final university thesis. I want to perform image processing algorithms (C-Code compiled for a DSP). I have the feeling that manual programming of this algorithms is no longer state of the art. Instead MDSD (model driven software development) - that means Code Generation - seems to be smarter to me. Unfortunately Mathworks offers no licenses of Matlab Coder (or Simulink Coder etc.) to individual students. And I cannot afford to buy a commercial license (which probably would cost me more than 5.000 EUR/$ / my absolute limit is 1.000 EUR/$). Is there any possibility for me to use MDSD (code generation) for image processing for my university thesis ? Maybe by using cheaper alternatives ? Or by using 3d party software (like target link) ? Or export/import to another product ? Any idea ? (I want to avoid manual coding - like using OpenCV) By the way, does anyone know, why Mathworks hides the MDSD features from students ? It doesn't make sense to me that Mathworks reduces the amount of engineers available on the job market that are capable of handling (serious) Matlab projects. (Microsoft offers the "Visual Studio Express Edition" for free for education and the amount of people on the job market that are experienced in Visual Studio is tremendous.). Thank you, Roelof ...

Hello, I recently purchased a Student edition of Matlab and installed it on a Windows PC. According to Mathworks, I can install Matlab on multiple computers. I wanted to also install it on a PC running Mac OS X; however, when I ran the installer and submitted the serial number, I got an error that prevented me from activating it on my Mac.

The Student Version of MATLAB shouldn't need a password -- the bookstore employee was probably thinking of the professional version of MATLAB, which does require a passcode or a license file. Chapter 2 of the Learning MATLAB 6 manual, which should have been included in the box, discusses how to install the Student Version. As long as you follow the instructions in that chapter and have your documentation CD in the drive when you start MATLAB, it should work. There is one issue that you may run into if your machine has a Pentium 4 -- see section 27 of this document for instructions on how to avoid this issue. http://www.mathwo...

I downloaded the MS visual C++ 2008 Express Edition and the SDK as detailed in http://www.mathworks.com/support/solutions/en/data/1-6IJJ3L/?solution=1-6IJJ3L My embedded function didnt work at the beginning because I did "mex -setup" before I installed my SDK. But after I installed the SDK, I ran "mex -setup" in Matlab once again and choose the MS visual C++2008 as my compiler. Then, my embedded matlab function worked.

Hi , I am profiling code in two different versions of MATLAB (2009a and 2012a). The machine 2012a is installed is newer than the machine with 2009a, and thus, a better CPU. However, when I execute the following: A=magic(10000) A.*A I received two different timing results, the 2009a results (414.0415 seconds) are much lower than 2012a (574.746 seconds). Any suggestion on why this is the case would be greatly appreciated. Also, all other subsecquent code in MATLAB 2012a is much lower than 2009a.

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 "Alex Cruikshank" <cruiksam@gmail.com> writes: > Long story short, here is the criteria I need. >...
