How to nest a cell array with existing cell array

Hi, I have a cell array Cells which is 1 x 190, and each cell is again a 1 x 20 cell array. Now for each cell in this 1 x 20 array I have to add two more cells which contain matrices. I tried doing Cells{1,1}{1,1}{1,1}=mymatrix; Cells{1,1}{1,1}{1,2}=mymatrix2; But I get an error Cell contents assignment to a non-cell array object. I am doing this in a loop like

for i =1:190
for j=1:20
Cells{1,i}{1,j}{1,1}=mymatrix;
Cells{1,i}{1,j}{1,2}=mymatrix2;
end
end

How can I also speed this up. Thanks

Cells = cell(1, 190);
for i1 = 1:190
  SubCell = cell(1, 20);
  for i2 = 1:20
    SubCell{i2} = {mymatrix, mymatrix2};
  end
  Cells{i1} = SubCell;
end

Should It have been Cells{1,i1}=Subcell, Right?

You are right, a typo. Fixed now. Cells{i1} is a tick faster than Cell{1, i1} with the same result.
