NAME
       SRC/cpptrs.f

SYNOPSIS
   Functions/Subroutines
       subroutine cpptrs (uplo, n, nrhs, ap, b, ldb, info)
           CPPTRS

Function/Subroutine Documentation
   subroutine cpptrs (character uplo, integer n, integer nrhs, complex,
       dimension( * ) ap, complex, dimension( ldb, * ) b, integer ldb, integer
       info)
       CPPTRS

       Purpose:


           !>
           !> CPPTRS solves a system of linear equations A*X = B with a Hermitian
           !> positive definite matrix A in packed storage using the Cholesky
           !> factorization A = U**H*U or A = L*L**H computed by CPPTRF.
           !>

       Parameters
           UPLO

           !>          UPLO is CHARACTER*1
           !>          = 'U':  Upper triangle of A is stored;
           !>          = 'L':  Lower triangle of A is stored.
           !>

           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 triangular factor U or L from the Cholesky factorization
           !>          A = U**H*U or A = L*L**H, packed columnwise in a linear
           !>          array.  The j-th column of U or L is stored in the array AP
           !>          as follows:
           !>          if UPLO = 'U', AP(i + (j-1)*j/2) = U(i,j) for 1<=i<=j;
           !>          if UPLO = 'L', AP(i + (j-1)*(2n-j)/2) = L(i,j) for j<=i<=n.
           !>

           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
           !>
