# tril (Matlab function)

Lower triangular part of a matrix

## Matlab/Scilab equivalent

Matlab | Scilab

    tril

    tril

## Particular cases

In L=tril(X) and L=tril(X,k), Scilab function gives different results from Matlab one if X is a String matrix. In this case use mtlb_tril 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.
