Reshape a 2D matrix to a 3D matrix

I have a (25 x 53515) matrix

I like to reshape it to 25 X 1 in the 2D domain so it will have 53515 layers in the 3D domain, thus forming a 25 x 1 x 53515 matrix.

How should I go about doing this?

reshape(yourarray,size(yourarray,1),1,[]);

other way

permute(yourarray,[1 3 2]);
