Function/Subroutine Documentation
   subroutine csytrs_rook (character uplo, integer n, integer nrhs, complex,

       Purpose:


           !>
           !> CSYTRS_ROOK solves a system of linear equations A*X = B with
           !> a complex symmetric matrix A using the factorization A = U*D*U**T or
           !> A = L*D*L**T computed by CSYTRF_ROOK.
           !>

       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**T;
           !>          = 'L':  Lower triangular, form is A = L*D*L**T.
           !>

           NRHS

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

           A

           !>          A is COMPLEX array, dimension (LDA,N)
           !>          The block diagonal matrix D and the multipliers used to
           !>          obtain the factor U or L as computed by CSYTRF_ROOK.
           !>

           LDA

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

           IPIV

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

           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
