SYNOPSIS

       SUBROUTINE CHPTRS( UPLO, N, NRHS, AP, IPIV, B, LDB, INFO )

           CHARACTER      UPLO

           INTEGER        INFO, LDB, N, NRHS

           INTEGER        IPIV( * )

           COMPLEX        AP( * ), B( LDB, * )

PURPOSE

       CHPTRS  solves  a  system  of  linear  equations A*X = B with a complex Hermitian matrix A
       stored in packed format using the factorization A = U*D*U**H or A = L*D*L**H  computed  by
       CHPTRF.

ARGUMENTS

        UPLO    (input) CHARACTER*1
                Specifies whether the details of the factorization are stored
                as an upper or lower triangular matrix.
                = 'U':  Upper triangular, form is A = U*D*U**H;
                = 'L':  Lower triangular, form is A = L*D*L**H.

        N       (input) INTEGER
                The order of the matrix A.  N >= 0.

        NRHS    (input) INTEGER
                The number of right hand sides, i.e., the number of columns
                of the matrix B.  NRHS >= 0.

        AP      (input) COMPLEX array, dimension (N*(N+1)/2)
                The block diagonal matrix D and the multipliers used to
                obtain the factor U or L as computed by CHPTRF, stored as a
                packed triangular matrix.

        IPIV    (input) INTEGER array, dimension (N)
                Details of the interchanges and the block structure of D
                as determined by CHPTRF.

        B       (input/output) COMPLEX array, dimension (LDB,NRHS)
                On entry, the right hand side matrix B.
                On exit, the solution matrix X.

        LDB     (input) INTEGER
                The leading dimension of the array B.  LDB >= max(1,N).

        INFO    (output) INTEGER
                = 0:  successful exit
                < 0: if INFO = -i, the i-th argument had an illegal value
