SYNOPSIS
   Functions/Subroutines
       subroutine zhetrs_rook (uplo, n, nrhs, a, lda, ipiv, b, ldb, info)
           ZHETRS_ROOK computes the solution to a system of linear equations A

           the bounded diagonal pivoting methods (max 2 interchanges)

Function/Subroutine Documentation
   subroutine zhetrs_rook (character uplo, integer n, integer nrhs,
       complex*16, dimension( lda, * ) a, integer lda, integer, dimension( * )
