## SYNOPSIS

- INTEGER FUNCTION

  ILAUPLO( UPLO )

- CHARACTER

  UPLO

## PURPOSE

This subroutine translated from a character string specifying a upper- or lower-triangular matrix to the relevant BLAST-specified integer constant. ILAUPLO returns an INTEGER.  If ILAUPLO \< 0, then the input is not a character indicating an upper- or lower-triangular matrix. Otherwise ILAUPLO returns the constant value corresponding to UPLO.
