I have the following Sparse Matrix E with the following redundant elements i.e (2,1) = (1,2), (5,1) = (1,5), (2,3)=(3,2) and (2,4) = (4,2)
E =
(2,1) 2.33
(5,1) 4.16
(1,2) 2.33
(3,2) 2.08
(4,2) 4.33
(1,5) 4.16
(2,3) 2.08
(2,4) 4.33
I want my sparse matrix output to be as follows
E =
(1,2) 2.33
(1,5) 4.16
(2,3) 2.08
(2,4) 4.33

E = triu(E);

@Bruno Luong It's gives the result correct but not in the ascending order sequence. Can you do any further modification in it.
