SYNOPSIS
   Functions/Subroutines
       subroutine cspt03 (uplo, n, a, ainv, work, ldw, rwork, rcond, resid)
           CSPT03

Function/Subroutine Documentation
   subroutine cspt03 (character uplo, integer n, complex, dimension( * ) a,
       complex, dimension( * ) ainv, complex, dimension( ldw, * ) work,
       integer ldw, real, dimension( * ) rwork, real rcond, real resid)
       CSPT03

       Purpose:


           !>
           !> CSPT03 computes the residual for a complex symmetric packed matrix
           !> times its inverse:
           !>    norm( I - A*AINV ) / ( N * norm(A) * norm(AINV) * EPS ),
           !> where EPS is the machine epsilon.
           !>

       Parameters
           UPLO

           !>          UPLO is CHARACTER*1
           !>          Specifies whether the upper or lower triangular part of the
           !>          complex symmetric matrix A is stored:
           !>          = 'U':  Upper triangular
           !>          = 'L':  Lower triangular
           !>

           N

           !>          N is INTEGER
           !>          The number of rows and columns of the matrix A.  N >= 0.
           !>

           A

           !>          A is COMPLEX array, dimension (N*(N+1)/2)

           !>          triangular matrix.
           !>

           AINV

           !>          AINV is COMPLEX array, dimension (N*(N+1)/2)
           !>          The (symmetric) inverse of the matrix A, stored as a packed
           !>          triangular matrix.
           !>

           WORK

           !>          WORK is COMPLEX array, dimension (LDW,N)
           !>

           LDW

           !>          LDW is INTEGER
           !>          The leading dimension of the array WORK.  LDW >= max(1,N).
           !>

           RWORK

           !>          RWORK is REAL array, dimension (N)
