Concatenation for a large number of 2D matrices

1 view (last 30 days)
i have around 151 2D matrices that i have to concatenate to form a 3D matrices. one option is to use the command c=cat (3,A1,A2,A3,A4,A5.......,A151). Is there an easier way to do it using some loop.

It all depends on how your matrices are named, assuming they all have the same size (number of rows and cols). If your matrices are within a cell array where each cell contains a matrix:
big_mat = zeros(rows,cols, 3);
for k = 1:151
big_mat(:,:,k) = A{k};
end
