Hello,
I have one image matrix A, 512 x 512, and I have another matrix, B 8x8,
I want to transform matrix B, 8x8 matrix, into a 512x512 matrix by repeating the values over and over.
How can I do this?
Alternatively, how can I divide every 8x8 section of matrix A by matrix B ?
Thank you

Ran in:
B = reshape(1:64, 8, 8); % generate B matrix
A = repmat(B, [32 32]); % repeating 32x32
imagesc(A)
