MATLAB: How to reshape each column of a matrix

code

I have a matrix of size 262144×243. I want to reshape each column into 512×512. Such that there are 243 matrices of 512×512 size.

reshape(A,512,[],243)

It depends on how you want the (120x1) matrix to look. Here are two possibilities:

A = [1:5; 6:10];
B1 = reshape(A, [], 1);
B2 = reshape(A', [], 1);

bsxfun(@times,permute(A,[1,3,2]),permute(B,[3,1,2]))

or using MATAB R2016b and newer:

permute(A,[1,3,2]) .* permute(B,[3,1,2])
