I have image matrix A (3dim matrix) which is (size1 x size2 x size3). (size1 x size2) is the image and size3 is number of images. I want to reshape matrix A so it will be ( (size1*size2) X 1 X size3 ) matrix. meaning it each image will turn to (size1* size2) column vector, and I will have size3 images like this. (so it will still be 3dim matrix) I know how to do this in a for loop running on size3, but is there a better way to do this?
Thanks.

newA = reshape(A, [], 1, size(A,3));
