replicate values of a vector

Dear all,

I have, say the vector A=(1:12)'; and I want to replicate each of the 12 numbers 4 times. Any simple code for this?

thanks in advance

Hi,

try repmat:

repmat(A,4,1)

Or for the other direction:

repmat(A,1,4)

In the case you want it repeated like this: [1 1 1 1 2 2 2 2 ....] you can use repmat and reshape:

reshape(repmat(A,4,1),[],1)
