I am trying to not use repmat() because I want to actually understand what is going on with this...

arr = [a b; c d]
row = 2;
col = 3;

I want to return this value..

new = [a b a b a b
       c d c d c d
       a b a b a b
       c d c d c d]

I feel like I have to use forloop in order to solve this but I dont have a clear idea...

Why not just admit it’s a homework?

Another option would be,

kron(ones(row,col),arr)
