Multi-threading in MATLAB

Question

I have read MATLAB\'s info on multi-threading and how it is in-built in certain functions. However, my requirement is different. Say, I have 3 functions: fun1(data1), fun2(

Answer 1

If you want to run a batch of different functions on different processors, you can use the Parallel Computing Toolbox, more specifically, a parfor loop, but you need to pass the functions as a list of handles.

funList = {@fun1,@fun2,@fun3};
dataList = {data1,data2,data3}; %# or pass file names 

matlabpool open 

parfor i=1:length(funList)
    %# call the function
    funList{i}(dataList{i});
end

Edit: Starting with R2015a matlabpool function has been removed from Matlab, you need to call parpool instead.

Answer 2

Try looking at the Parallel Computing Toolbox. (I'm unfortunately not too familiar with it, but that seems to be the right place.) Look at gather and parallel for-loops.
