Matlab for loop
Matlab for loop
(OP)
Hi everyone,
i'm working on a code which has two 5*3 matrices,I want to add each column in say matrix "A" to every column in matrix "B"
so the resultant matrix is 5*9.
I'm doing it with FOR loop but it only returns the final column values. I hope if there are any suggestions!

RE: Matlab for loop
Out_matrix=zeros(5,9);
for jj=0:2
for kk=1:3
Out_matrix(:,(jj*3)+kk)=A(:,jj+1)+B(:,kk);
end
end
Cheers

RE: Matlab for loop
1) Pre-allocate your array (Greg's first line). Never grow it.
2) Realise that the neat and satisfying one-liners (vectorized solutions) don't have as much advantage over loops these days.

This isn't making sense; there are no intermediate values.
TTFN (ta ta for now)
I can do absolutely anything. I'm an expert! https://www.youtube.com/watch?v=BKorP55Aqvg
