(copy of prob. 859)

In this problem you must submit a solution which returns the diagonal and anti-diagonal elements without using the DIAG function for any m-by-n matrix

Example:

If the input is a 4x3 matrix

x =  [ 0     0     0
       1    48    17
       0     2    99
       14    0    3]

we expect 2 output vectors:

dg_elements = [0 48 99] % diagonal elements

antidg_elements = [14 2 17 ] % anti-diagonal elements

Note that the anti-diagonal starts from the bottom left corner.
