This function takes as an input a square matrix and returns two outputs. The first is a vector containing the matrix values starting in the (1,1) entry and progressing along the anti-diagonal elements. A second output gives the sum of the elements along the anti-diagonals.
For example:
a = [1 2 3; 4 5 6; 7 8 9];
[b,c] = diagtrav(a);
b = [1 2 4 3 5 7 6 8 9];
c = [1 6 15 14 9];
