MATLAB: Cell 2 Multidimensional Array Conversion

catcell arraysmultidimensional arrays

Hi, I have a 420 X 1 cell array, A, and each cell contains an 70000 x 100 matrix,How can I get 420 X 70000 X 100 ?

out = permute(cat(3,A{:}),[3,1,2]);

B = permute(cat(3,A{:}),[3,1,2])

so?

for j1 = 1:size(A,1)
    fprintf(['combinations ',num2str(j1),' = ',mat2str(combinations(:,:,j1)),'\n']); 
end
