read and use the ith matrix for the ith determiner

Hello All,

I want to use parfor loop to speed up my calculations. However I am stuck at a point. for each determiner, a certain predefined matrix has to be used. Please be advised that the matrices are not dimensional equal so that I cannot combine them all together.

Assume I have matrices R1, R2 and R3 with totally different dimensions. I want to do the following:

parfor i=1:3
read matrix Ri % I do not know how to do this part
my calculations
end

What should i do? Thank you so much

Easy: put the matrices into one cell array. This is a fast and reliable way to program:

C = {R1,R2,R3}; % <- one cell array
parfor k = 1:numel(C)
    C{k}
end

And DO NOT try to access those arrays using dynamic variable names. That would be a slow and buggy way to program, that beginners seem to love no matter how slow and buggy it is:
