Matlab data transformation

Hi professor;
I am wondering how to tranform matrix 1 in the top into matrix 2 in the bottom using matlab?

you could refer them as A and B,
each colum of B repeats each colum of A 3 times.

Best

Hi,

You can use the repmat fonction:

B = repmat(A, 3, 1);

or a kronecker product.

Best,
Stéphane.
