Argument Declarations

Type, dimension and description for variables occurring in the subroutine specifications are as follows:

   CHARACTER*1        SIDE, UPLO, TRANS, TRANSA, TRANSB, DIAG
   INTEGER            IA, IB, IC, INCX, INCY, INDX, IX, IY
   INTEGER            JA, JB, JC, JX, JY, M, N, K
   INTEGER            DESCA( 8 ), DESCB( 8 ), DESCC( 8 )
   INTEGER            DESCX( 8 ), DESCY( 8 )

For routines whose second letter is a S:

   REAL               ALPHA, AMAX, ASUM, BETA, DOT, NRM2
   REAL               A( * ), B( * ), C( * ), X( * ), Y ( * )

For routines whose second letter is a D:

   DOUBLE PRECISION   ALPHA, AMAX, ASUM, BETA, DOT, NRM2
   DOUBLE PRECISION   A( * ), B( * ), C( * ), X( * ), Y ( * )

For routines whose second letter is a C:

   REAL               AMAX, ASUM, DOTC, DOTU, NRM2
   COMPLEX            ALPHA, BETA
   COMPLEX            A( * ), B( * ), C( * ), X( * ), Y ( * )

except for PCHER and PCHERK where the scalars and are real so that the first declaration above is replaced by:

   REAL               ALPHA, BETA

and for PCHER2K is complex and is real, so this is replaced by:

   COMPLEX            ALPHA
   REAL               BETA

For routines whose second letter is a Z:

   DOUBLE PRECISION   AMAX, ASUM, DOTC, DOTU, NRM2
   COMPLEX*16         ALPHA, BETA              
   COMPLEX*16         A( * ), B( * ), C( * ), X( * ), Y( * )

   DOUBLE PRECISION   AMAX, ASUM, DOTC, DOTU, NRM2
   DOUBLE COMPLEX     ALPHA, BETA
   DOUBLE COMPLEX     A( * ), B( * ), C( * ), X( * ), Y( * )

except for PZHER and PZHERK where the scalars and are real so that the first declaration above is replaced by:

   DOUBLE PRECISION   ALPHA, BETA

and for PCHER2K where is complex and is real, so this is replaced by:

   COMPLEX*16         ALPHA
   DOUBLE PRECISION   BETA

   DOUBLE COMPLEX     ALPHA
   DOUBLE PRECISION   BETA
