MATLAB: Matrix repetition

Question

Hello,

I have a matrix M of dimensions (m by n). I want to repeat this matrix 'k' number of times along the column.

For example:

If

M=[1 3 4 5;4 5 6 7;9 3 4 2]

and k=4(say),then

out=[1 3 4 5 1 3 4 5 1 3 4 5 1 3 4 5;4 5 6 7 4 5 6 7 4 5 6 7 4 5 6 7;9 3 4 2 9 3 4 2 9 3 4 2 9 3 4 2]

please help.

Answer 1

   out = repmat(M,1,k);
