Hi, I have a 3D matrix with a size of 256x256x256. I would like to delte the first plane (so in 2D) seen from the top, the bottom, from left and from right. How can I compute this using matlab?

Sometimes it is simpler to take what you want, than it is to delete what you don't want. Here is a matrix:
A = rand(256,256,256);
Clearly you know the size.
B = A(2:255,2:255,2:255);
Which elements are no longer present in B compared to A? If you don't want to create a new matrix, then just assign the result back into the variable A.
