How can I create a matrix from a repeated vector.
For example, I have
a=[ 1 2 3 4 5 6 7 ];
How can I create the following matrix
A=[1 2 3 4 5 6 7
1 2 3 4 5 6 7
1 2 3 4 5 6 7
1 2 3 4 5 6 7
1 2 3 4 5 6 7
1 2 3 4 5 6 7 ];

I can use a for loop, but I am wondering if there is a better way to do so.

Thanks

I already tried to use repmat but it did not give me what I am need. Probably because it will Replicate and tile.

How should I use repmat in this case ?

Thanks

repmat(a,floor(exp(pi)),1)
