MATLAB: How to put a double array of random dimension inside a cell array

Question

I'm going to make an example, I have a double array A [2501 x 4000] and a cell array B [10 x 1] of empty cells. I want to have that B(1,1) = A so that the first cell of B will become A. However, when I tried like above, I obtained this error "Conversion to cell from double is not possible." How can I solve this?

Answer 1

B{1,1} = A

or

B(1,1) = {A}
