Avoid reading diagonal and redundant symmetric elements

2 views (last 30 days)
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

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