# Form a big matrix from small matrices

## Form a big matrix from small matrices

(OP)
Hi all,

Anyone knows how to form a matrix as below:

bigC = [
C0       C1     C2     ......     C(n-1)
C1       C0     C1     ......     C(n-2)
C2       C1     C0     ......     C(n-3)
......................................
C(n-1) C(n-2)  C(n-3)  ......     C0     ]            ???

where Ci's are square matrices.

The toeplitz command works well if Ci's are numbers, for example:
c = [1  2  3  4  5];
r = [1  2  3  4  5];
toeplitz(c,r)

ans =

1     2     3     4     5
2     1     2     3     4
3     2     1     2     3
4     3     2     1     2
5     4     3     2     1

Any suggestions if Ci's are matrices?
Thanks

### RE: Form a big matrix from small matrices

I'd just write a couple of for loops but there is probably a better way, 'cell' looks relevant.

Cheers
