Matlab repmat into long single dismension array?

I'm trying to take: 

a = [1 2 3]

and repeat it 5 times to get: 

b = [1 2 3 1 2 3 1 2 3 1 2 3 1 2 3]

but when I try: 

b = repmat(a, 5, 1)

instead I get: 

 b =

 1     2     3
 1     2     3
 1     2     3
 1     2     3
 1     2     3

I could probably do it with a for loop but I'd like to do it correctly if possible. Any suggestions? Thanks in advance

Solution

  • Use the following code:

    b = repmat(a,1,5)

    The numbers '1' and '5' refer to the amount of rows and columns that you want to repeat the matrix a. The order is important.
