Hello everyone,
I want to formulate a very big square matrix, in which every element is again a square matrix. I want the sqaure matrix element being as an element to fill up the big one. Any idea for formulating this big matrix, please?
Thanks very much for your kind help.

A = magic(3) ;
B = cell(5,5) ;
B(:) = {A} ;
B = cell2mat(B)

Hi, my matrix size is large, i need to use loop to conduct this formulation. So how can I put each element A into a bracket and assign {A} to B(i,j), please?

hi, may i have a follow up question about the command "cell2mat":
if i have that A = {B}, and B={C}. how can i finally expresse A into a matrix ?
