LA_LAMCH Interfaces

LAPACK95 has two kinds of interface entries for LA_LAMCH.
  1. Explicit interface entries:
    
     INTERFACE 
    
    FUNCTION SLAMCH( CMACH )
    USE LA_PRECISION, ONLY: WP $=>$ SP
    REAL(WP) :: SLAMCH
    CHARACTER( LEN = 1 ), INTENT( IN ) :: CMACH
    END FUNCTION SLAMCH
    FUNCTION DLAMCH( CMACH )
    USE LA_PRECISION, ONLY: WP $=>$ DP
    REAL( WP ) :: DLAMCH
    CHARACTER( LEN = 1 ), INTENT( IN ) :: CMACH
    END FUNCTION DLAMCH
    END INTERFACE
    This is a part of the F77_LAPACK interface module blocks.
  2. Generic interface entry:
    
     FUNTION LA_LAMCH( 1.0_wp, CMACH, INFO ) 
    
    CHARACTER(LEN=1), INTENT( IN ) :: CMACH
    REAL(wp) :: LA_LAMCH
    INTEGER, INTENT( OUT ), OPTIONAL :: INFO
    where
    wp ::= KIND( 1.0 ) $\mid$ KIND( 1.0D0 )
    This is a part of the F95_LAPACK interface module blocks.

For function values of LA_LAMCH (SLAMCH and/or DLAMCH) see Table 1.1.
