Problem 1853. Enlarge array
Given an m-by-n numeric array (A) and a 1-by-2 vector (sz) indicating the dimensions [p q] to enlarge each element, return an (m*p)-by-(n*q) array (B) in which each element of A has been replicated in p rows and q columns.
Example
If
A = [1 2 3 4 5 6 7 8 9] sz = [3 2]
then
B = [1 1 2 2 3 3 1 1 2 2 3 3 1 1 2 2 3 3 4 4 5 5 6 6 4 4 5 5 6 6 4 4 5 5 6 6 7 7 8 8 9 9 7 7 8 8 9 9 7 7 8 8 9 9]
