Problem 859. Get the elements of diagonal and antidiagonal for any m-by-n matrix
In the problem Problem 858. Permute diagonal and antidiagonal created by Jean-Marie SAINTHILLIER the test suite is only based on squared m-by-m matrix .
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 matrix 4*3
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 : You do not have to permute anything. Just return the elements.

I really don't see the point of that kind of problems where you can't use Matlab built-in functions.
which functions?
