converting 3d matrix into a cell array

Hi,

I have a 3D matrix (1001x 259x 259) and want to convert to a cell array (1x1001) in which each cell array has 259x259 matrix (2D matrix). Could anyone help?

Thanks.

I tried the below code from this forum

https://www.mathworks.com/matlabcentral/answers/344044-transform-a-3d-matrix-into-cell-array

Mycell = num2cell(Mymatrix,[2 3]);

But I want the 2D matrix inside each cell array.

@AT_HYZ, change the dimensions and use the above transformation -

abc = rand(1001,259,259);

%Shift dimensions
Mymatrix = shiftdim(abc, 1);
%Check size
size(Mymatrix)

ans = 1x3

259 259 1001

%Use num2cell
Mycell = num2cell(Mymatrix,[1 2]);
size(Mycell)

ans = 1x3

1 1 1001

%Change the size of the cell array as required
Mycell = reshape(Mycell, 1, 1001);

%Check the size of data inside a cell element
size(Mycell{1})

ans = 1x2

259 259

x = rand(1001,259,259);
result = arrayfun(@(k)squeeze(x(k,:,:)),1:size(x,1),'uni',false);
size(result)

ans = 1x2

1 1001

size(result{1})

ans = 1x2

259 259

But, be advised that for matrix manipulation it might be better to keep this data as a 3D array with dimensions 259x259x1001 (i.e., permute(x,[2 3 1])) so that you can take advantage of the page functions like pagemtimes, pagemldivide, etc.
