*       .. Scalar Arguments ..
*       INTEGER            INDA, N, VINDA

*
*> \par Purpose:
*  =============
*>
*> \verbatim
*>
*> CLAIPD sets the imaginary part of the diagonal elements of a complex
*> matrix A to a large value.  This is used to test LAPACK routines for
*> complex Hermitian matrices, which are not supposed to access or use
*> the imaginary parts of the diagonals.
*> \endverbatim
*
*  Arguments:
*  ==========
*
*> \param[in] N
*> \verbatim
*>          N is INTEGER
*>         The number of diagonal elements of A.
*> \endverbatim
*>
*> \param[in,out] A
*> \verbatim
*>          A is COMPLEX array, dimension
*>                        (1+(N-1)*INDA+(N-2)*VINDA)
*>         On entry, the complex (Hermitian) matrix A.
*>         On exit, the imaginary parts of the diagonal elements are set
*>         to BIGNUM = EPS / SAFMIN, where EPS is the machine epsilon and
*>         SAFMIN is the safe minimum.
*> \endverbatim
*>
*> \param[in] INDA
*> \verbatim
*>          INDA is INTEGER
*>         The increment between A(1) and the next diagonal element of A.
*>         Typical values are
*>         = LDA+1:  square matrices with leading dimension LDA
*>         = 2:  packed upper triangular matrix, starting at A(1,1)
*>         = N:  packed lower triangular matrix, starting at A(1,1)
*> \endverbatim
*>
*> \param[in] VINDA
*> \verbatim
*>          VINDA is INTEGER
*>         The change in the diagonal increment between columns of A.
*>         Typical values are
*>         = 0:  no change, the row and column increments in A are fixed
*>         = 1:  packed upper triangular matrix
*>         = -1:  packed lower triangular matrix
