INTEGER FUNCTION ILATRANS( TRANS )
*
* -- LAPACK routine (version 3.2) --
*
* -- April 2009 --
*
* -- LAPACK is a software package provided by Univ. of Tennessee, --
* -- Univ. of California Berkeley, Univ. of Colorado Denver and NAG Ltd..--
*
* .. Scalar Arguments ..
CHARACTER TRANS
* ..
*
* Purpose
* =======
*
* This subroutine translates from a character string specifying a
* transposition operation to the relevant BLAST-specified integer
* constant.
*
* ILATRANS returns an INTEGER. If ILATRANS < 0, then the input is not
* a character indicating a transposition operator. Otherwise ILATRANS
* returns the constant value corresponding to TRANS.
*
* Arguments
* =========
*
* TRANS (input) CHARACTER*1
* Specifies the form of the system of equations:
* = 'N': No transpose
* = 'T': Transpose
* = 'C': Conjugate transpose
* =====================================================================
*
* .. Parameters ..
INTEGER BLAS_NO_TRANS, BLAS_TRANS, BLAS_CONJ_TRANS
PARAMETER ( BLAS_NO_TRANS = 111, BLAS_TRANS = 112,
$ BLAS_CONJ_TRANS = 113 )
* ..
* .. External Functions ..
LOGICAL LSAME
EXTERNAL LSAME
* ..
* .. Executable Statements ..
IF( LSAME( TRANS, 'N' ) ) THEN
ILATRANS = BLAS_NO_TRANS
ELSE IF( LSAME( TRANS, 'T' ) ) THEN
ILATRANS = BLAS_TRANS
ELSE IF( LSAME( TRANS, 'C' ) ) THEN
ILATRANS = BLAS_CONJ_TRANS
ELSE
ILATRANS = -1
END IF
RETURN
*
* End of ILATRANS
