use of cell arrays to store matrices... but parfor gives an error
显示 更早的评论
Hi,
I've got a loop which creates three matrices, and I want to store these for each iteration. Previously I've been saving them as indexed files, but I've just discovered cell arrays which appear to be ideal for this purpose.
My code looks like this:
mat_array = cell(3,50);
parfor i = 1:50
[A,B,C] = matrixgenerator(~);
mat_array {1,i} = A;
mat_array {2,i} = B;
mat_array {3,i} = C;
end
However, I'm getting an error message that mat_array is "indexed in different way, potentially causing dependencies between iterations". I don't understand this error, and don't see where any conflict could arise. Can anyone help me with a workaround?
Thanks

Try:
mat_array = cell(3,50);
parfor i = 1:50
[a,b,c] = matrixgenerator(~);
mat_array(:,i) = {a,b,c};
end
In this way, you're performing a single indexing operation into mat_array, in a way that the PARFOR infrastructure can understand (i.e. the subscripts are a combination of the loop variable, and the literal ':').
