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)
