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.

ARGUMENTS

= 'U': A is upper triangular; = 'L': A is lower triangular.
