Thread Subject: Copying rows of numbers

Hello,

If i have the following:

ans = 2 6 8 10 4 12 7 8

which is a 1x8 matrix

How can i copy the row of numbers so i have the following:

ans = 2 6 8 10 4 12 7 8
         2 6 8 10 4 12 7 8
         2 6 8 10 4 12 7 8
         2 6 8 10 4 12 7 8

i.e. i would like to copy the 1x8 matrix to make a 4x8 matrix with the numbers in rows 2,3 and 4 the same as the ones in row 1.

Any help would be great.

Thanks,

Phil

Use repmat:

A=[2 6 8 10 4 12 7 8];
B=repmat(A,4,1);

     v=1:6;
     m=v(ones(4,1),:)
%{
     1 2 3 4 5 6
     1 2 3 4 5 6
     1 2 3 4 5 6
     1 2 3 4 5 6
%}
