NAME
       zpbtrs.f -

SYNOPSIS
   Functions/Subroutines
       subroutine zpbtrs (UPLO, N, KD, NRHS, AB, LDAB, B, LDB, INFO)
	   ZPBTRS

Function/Subroutine Documentation
   subroutine zpbtrs (characterUPLO, integerN, integerKD, integerNRHS, complex*16, dimension( ldab, * )AB, integerLDAB, complex*16, dimension(
       ldb, * )B, integerLDB, integerINFO)
       ZPBTRS

       Purpose:

	    ZPBTRS solves a system of linear equations A*X = B with a Hermitian
	    positive definite band matrix A using the Cholesky factorization
	    A = U**H *U or A = L*L**H computed by ZPBTRF.

       Parameters:
	   UPLO

		     UPLO is CHARACTER*1
		     = 'U':  Upper triangular factor stored in AB;
		     = 'L':  Lower triangular factor stored in AB.

	   N

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

	   KD

		     KD is INTEGER
		     The number of superdiagonals of the matrix A if UPLO = 'U',
		     or the number of subdiagonals if UPLO = 'L'.  KD >= 0.

	   NRHS

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

	   AB

		     AB is COMPLEX*16 array, dimension (LDAB,N)
		     The triangular factor U or L from the Cholesky factorization
		     A = U**H *U or A = L*L**H of the band matrix A, stored in the
		     first KD+1 rows of the array.  The j-th column of U or L is
		     stored in the j-th column of the array AB as follows:
		     if UPLO ='U', AB(kd+1+i-j,j) = U(i,j) for max(1,j-kd)<=i<=j;
		     if UPLO ='L', AB(1+i-j,j)	  = L(i,j) for j<=i<=min(n,j+kd).

	   LDAB

		     LDAB is INTEGER
		     The leading dimension of the array AB.  LDAB >= KD+1.

	   B

		     B is COMPLEX*16 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
