MATLAB: Avoid reading diagonal and redundant symmetric elements

Question

Hello,

I would like to create a matlab function that reads matrix elements and print only those elements which are non diagonal and redundant.

For example,

A = [

1 2 3

2 5 6

3 6 7]

The function should only print; 2, 3, 6

Thank you a lot

Answer 1

use tril or triu function to get the lower or upper triangular matrix. Or use diag to get nonmain diagonal elements.
