I have a matrix of N x M x Z 3D matrix. Where N x M is 2 x 100 and Z is 500. I want to convert it into cell array of Z x 1 ( 500 x 1) where each cell element will be N x M (2 x 100). How I can do this?

A = rand(2,100,500); % example data
C = squeeze(num2cell(A,[1 2])); % create cell array
whos C
isequal(cat(3,C{:}),A) % verify

A = rand(500,2,100);
C = num2cell(A,[2 3]); % line 1
At this point, each elment of C is 1 x 2 x 100 and is isequal to the corresponding slice of A. For example
size(C{293})
isequal(C{293},A(293,:,:))
To make each cell 2 x 100
C = cellfun(@(c) squeeze(c),C,'UniformOutput',false); % line 2
size(C)
size(C{293})
isequal(C{293},squeeze(A(293,:,:)))
Lines 1 and 2 can be combined into a single line if desired.
There may be a better way to do this.
