matrix - Matlab Repeat Value

Question

I this matrix:

A = [2 3 4 6 7 8 9 1 2];

I need to change that matrix into:

B = [2 3 4 6 7 8 9 1 2;
     2 3 4 6 7 8 9 1 2;
     2 3 4 6 7 8 9 1 2]

the output will be:

B =

 2     3     4     6     7     8     9     1     2
 2     3     4     6     7     8     9     1     2
 2     3     4     6     7     8     9     1     2

Thank you so much...

repmat and repelem are used for repeating the copies of an array. For your case, you can use either of these as: repmat(A,3,1) or repelem(A,3,1)
