MATLAB: How to change cell array to matrix

cell arrayMATLABmatrix

This question has been asked several times but none of the answers have helped me so far.

I have a cell array, C, that is 5 x 6 with each cell being 1 x 1.

How do I get a resulting 5 x 6 matrix with all indices being treated as numbers? I have used cell2mat(C) but that just results in the error 'Dimensions of matrices being concatenated are not consistent.' Shouldn't this work since each cell is 1 x 1?

The numbers are stored as character arrays, the reason the dimensions did not match.

Simply convert them to a numeric array:

N = str2double(A1)

MATLAB: I have a cell array of size 1×934 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 160×160

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,[]);
