Dividing matrices of different dimensions

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

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