Question

I have a cell array C containing 380 matrices and want to put them in 3-dimensional matrix M
such that the 1st 20 matrices of C will be in M(:,:,1), the 2nd 20 matrices (from 21 to 40) in M(:,:,2) and so on.

Edit: I want to concatenate them columnwise.

Can I do this in a one loop in Matlab.

Answer 1

You don’t even need a loop for that:

%# C: cell array with 380 elements

%# reshape C to 20x1xn
C = reshape(C,20,1,[]);

%# create matrix M
M = cell2mat(C);
