Hi guys, mx is a 100x61 cell array. I want to replicate the numbers of all cells in the cell array with the following formula but i get the following error:
n=61
for f = 1:n
for k=1:length(mx)
myCells{k,f} = [mx{k,f} ((kron([mx{k,f}], ones(4,1))))];
end
end
Error using horzcat Dimensions of matrices being concatenated are not consistent.
I tried many things to correct it but it didnt help. can anyone help.

You can't concatenate horizontally matrices with a different numbers rows, no matter what.
Since your kron creates a matrix with the same numbers of columns, you can do the concatenation vertically as in my answer.
Once again, this has nothing to do with cell arrays and the size of the cell array is irrelevant. It's simply to do with matrix concatenation.

This is possibly what you want:
for ...
for ...
mycells{k, f} = [mx{k,f}; kron(mk{k, f}, ones(4, 1))];
end
Note that the bounds of your loops don't look right. You could just replace the loops with a cellfun
mycells = cellfun(@(m) [m; kron(m, ones(4, 1)], mx, 'UniformOutput', false);
