How can i use toeplitz in cell arrays?

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

Its cell contains 38x38 matrix . So its a 2D toeplitz. Not 1D.

[Stephan]

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}

cell2mat(G(toeplitz(1:numel(G))))
