matlab删除数组的第三维，并将其分配给二维数组

Question

I have a 3 dimensional array. I want to assign only the first two dimensions to a 2D array.

The array is

A<44,512,3 uint8>

I need to drop the 3 and assign it to a new array B so that B would be

B<44,512 uint8>

I do not know how to proceed. Could someone please help me ?

Answer 1

Which 2D slice of your 3D array do you need? If you want slice #2, you do:

B = A(:,:,2);
