**SYNOPSIS**

INTEGER FUNCTION ILADIAG( DIAG ) CHARACTER DIAG

**PURPOSE**

This subroutine translated from a character string specifying if a matrix has unit diagonal or not to the relevant BLAST-specified integer constant. ILADIAG returns an INTEGER. If ILADIAG < 0, then the input is not a character indicating a unit or non-unit diagonal. Otherwise ILADIAG returns the constant value corresponding to DIAG.

**ARGUMENTS**

= 'N': A is non-unit triangular; = 'U': A is unit triangular. LAPACK routine (version 3.2.1) April 2011 ILADIAG(3lapack)
