repmat
B = repmat(A,<[r1,...,rN]>)specifies a list of scalars r1, …, rN, that describes how copies of A are arranged in each dimension- When A has N dimensions, the size of B is
size(A).*[r1 ... rN] - For example,
repmat([1 2; 3 4],2,3)returns a 4-by-6 matrix
- When A has N dimensions, the size of B is
