Hello All,

I have a [256 x 5 x 2000] matrix. I want to split this matrix into 5 [256 x 1 x 2000] matrices. Tried using mat2cell but it returns an error stating number of dimensions must match.

Could anyone please help me with this?

Thanks, \Kashif

The dimensions have to add to the same values in each dimension with mat2cell.

This works:

M = randi(9, 256, 5, 2000);                                         % Create Matrix
C = mat2cell(M, 256, ones(1,5), 2000);                              % Split To Cells

@Star Strider: Yeps this works...even if I do plot(squeeze(C{1}(1,1,:))); Thanks!

@ksnf3000: why are you using both num2cell and mat2cell? None of the answers do this. mat2cell splits up your array into pieces and returns a cell array... why do you want to split this up as well? You only need one of them.
