i have a matrix "A" which has to be concatenated 600 times to make a new matrix. please help me doing it

for example, i have a matrix B = [1 2], i want to create a matrix "C" which is matrix B concatenated 5 times

C = [B B B B B];

which would evaluate to [1 2 1 2 1 2 1 2 1 2]

what should i do to make it 600 times!!!!

Have you looked at repmat?

thank you Daniel

You are looking for the repmat function.

B = [1 2];
C = repmat(B,1,600)

This will repeat matrix B for 1 row and 600 columns.
