MATLAB: How to reshape and repeat at the same time.

Question

Hi guys, I have the following data

data= [1 3 7 9 2 5]

and I want the data to be as a matrix (2*6)

 newdata=1 1  7 7  2 2
         3 3  9 9  5 5

Please help me, and thanks in advance.

Answer 1

num_rows = 2;
num_copies = 2;
new_data = kron(reshape(data, num_rows, []), ones(1, num_copies));

Or less verbosely,

new_data = kron(reshape(data,2,[]),ones(1,2));
