I have a cell array of size 1x934 and each cell has 160x160x96 double. I want to make a cell array of 1xn (n i think it is 89664) where each cell has 160x160

Method one: concatenate into one numeric array, then split. This will not work of you do not have enough memory for the complete array. Where C is your cell array:

D = reshape(num2cell(cat(3,C{:}),1:2),1,[])

Method two: split into cell arrays, then concatenate. Does not require one large array to be sored in contiguous memory. Where C is your cell array:

D = cellfun(@(a)num2cell(a,1:2),C,'uni',0);
D = reshape(cat(3,D{:}),1,[]);

Answer 2

out = squeeze(num2cell(cat(3,C{:}),[1,2]));
