It's not clear how to divide a matrix with 640 elements by an array with 2808 elements. Can you show with a smaller concrete example exactly what you want/expect the result to be? For instance, for the following 16-by-4 y and 4-by-6-by-11 h:

y = reshape(1:64, [16 4]);
h = reshape((1:264)+64, [4 6 11]); % y and h have no elements in common

What exactly should A be?

i want to change matrix of 160 by 4 into 160 by 6 by 4 by adding zeros for dimension 6. and also change the second matrix(4 by 6 by 117) into (4 by 6 by 160) by adding zeros in 3rd dimension.
