Hey,

I have two matrix, A = [269338x2] and

B = [135194x1].

I would like to reduce the size of A to be the same size as B using a for loop.

for i = 1:2

A(:,i) = delayseq(A(:,i), 300);

A(:,i) = A(1:length(B));

end

but it doesnt work! any help??

Thanks!

Marwa

I don't think you need to use a for loop for this. Its unclear if you want something specific out of A. But if you just want to use a portion of A that is the same size as B, just get it out with indexing.
