# triu (Matlab function)

Upper triangular part of a matrix

## Matlab/Scilab equivalent

Matlab | Scilab

    triu

    triu

## Particular cases

In U=triu(X) and U=triu(X,k), Scilab function gives different results from Matlab one if X is a String matrix. In this case use mtlb_triu instead.

Note that k can be complex in Matlab, in this case, only real part of k is taken in account, Scilab gives an error message for a such use.
