chptrs.f(3)				      LAPACK				      chptrs.f(3)

NAME
       chptrs.f -

SYNOPSIS
   Functions/Subroutines
       subroutine chptrs (UPLO, N, NRHS, AP, IPIV, B, LDB, INFO)
	   CHPTRS

Function/Subroutine Documentation
   subroutine chptrs (characterUPLO, integerN, integerNRHS, complex, dimension( * )AP, integer,
       dimension( * )IPIV, complex, dimension( ldb, * )B, integerLDB, integerINFO)
       CHPTRS

       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.

       Parameters:
	   UPLO

		     UPLO is 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

		     N is INTEGER
		     The order of the matrix A.  N >= 0.

	   NRHS

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

	   AP

		     AP is 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

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

	   B

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

	   LDB

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

	   INFO

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