If ILADIAG < 0, then the input is not a *> character indicating a unit or non-unit diagonal. Otherwise ILADIAG *> returns the constant value corresponding to DIAG. *> \endverbatim * * Arguments: * ========== * * * Authors: * ======== * *> \author Univ. of Tennessee *> \author Univ. of California Berkeley *> \author Univ. of Colorado Denver *> \author NAG Ltd. * *> \ingroup auxOTHERcomputational * * ===================================================================== INTEGER FUNCTION ILADIAG( DIAG ) * * -- LAPACK computational routine -- * -- LAPACK is a software package provided by Univ. of Tennessee, -- * -- Univ. of California Berkeley, Univ. of Colorado Denver and NAG Ltd..-- * * ..
