Hello ,
i have 1x38 cell matrix and every cell contains a 38x38 matrix .I want to perform toeplitz() on this cell array but matlab cannot do that .
For example if my cell array is G then i want to create this toeplitz matrix :
G_toeplitz = [G{1} 0 0 0
G{2} G{1} 0 0
G{3} G{2} G{1} 0
G{4} G{3} G{2} G{1} .......
.
.
.
]
Is there any way to do this?

G = cell(1,2);
G{1} = ones(2);
G{2} = 2*ones(2);
c = [G{1} G{2}];
r = [G{1} zeros(2)];
result = toeplitz(c,r)
results in:
result =
1 1 1 1 0 0 0 0
1 1 1 1 1 0 0 0
1 1 1 1 1 1 0 0
1 1 1 1 1 1 1 0
2 1 1 1 1 1 1 1
2 2 1 1 1 1 1 1
2 2 2 1 1 1 1 1
2 2 2 2 1 1 1 1

In my example I used 2x2 matrices to keep it simple and short. Don't you think this can be extended to 38x38?
G{1}
G{2}
