I have a 9x256x21 single matrix that I would like to convert into a 2D matrix so that the new dimensions are 9x5376. The 5376 is a multiplication of 256*21. The third dimension (21) each represents 1 second and I just want to concatenate each second columnwise.
I am aware I most likely need to use the reshape function but am unsure how. Please help me! Thanks

Yes reshape will work
sz = size(A);
B = reshape(A,sz(1),[],1);
% or B = reshape(A,sz(1),sz(2)*sz(3));
