Problem 2062. A matrix of introverts

You are given a matrix full of numbers who happen to be very shy. Write a MATLAB function that will put a square of zeros around each term in the matrix, thus giving them the privacy and space they desire. This should include a border of zeros around the outside of the matrix.

For example, if your input matrix is magic(3):

 [8 1 6
  3 5 7
  4 9 2]

your output will be:

 [0 0 0 0 0 0 0
  0 8 0 1 0 6 0
  0 0 0 0 0 0 0
  0 3 0 5 0 7 0
  0 0 0 0 0 0 0
  0 4 0 9 0 2 0
  0 0 0 0 0 0 0]

Please help them out, but do so quietly; they don't like the attention very much.
