Can you make a circulant matrix of matrices
Posted:

Suppose I have an (nxn) matrix A made like this (when n=4):
v1=[4,1,0,1]; A1=gallery('circul',v1);
That gives me a 4x4 circulant matrix. Now, I want to make a circulant matrix of matrices. That is, how do I create a matrix that looks like this (augmented) matrix:
A=[A1 eye(4) zeros(4) eye(4); eye(4) A1 eye(4) zeros(4) ; zeros(4) eye(4) A1 eye(4) ; eye(4) zeros(4) eye(4) A1];
Is there an easy way to do that in Matlab?
