.RS 4

.PP
.nf
 ZPPTRS 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 ZPPTRF.

\fIUPLO\fP 
.PP
.nf
          UPLO is CHARACTER*1
          = 'U':  Upper triangle of A is stored;
          = 'L':  Lower triangle of A is stored.
.fi

\fIN\fP 
.PP
.nf
          N is INTEGER
          The order of the matrix A.  N >= 0.

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

\fIAP\fP 
.PP
.nf
          AP is COMPLEX*16 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.

.nf
          B is COMPLEX*16 array, dimension (LDB,NRHS)
          On entry, the right hand side matrix B.
          On exit, the solution matrix X.
