sppsl

NAME

sppsl - (obsolete) solve the linear system Ax = b for a symmetric positive definite matrix A in packed storage, which has been Cholesky-factored by SPPCO or SPPFA, and vectors b and x.

SYNOPSIS

  SUBROUTINE SPPSL( A, N, B)
  INTEGER N
  REAL A(*), B(*)
 
  SUBROUTINE SPPSL_64( A, N, B)
  INTEGER*8 N
  REAL A(*), B(*)

C INTERFACE

#include <sunperf.h>

void sppsl(float *a, int n, float *b);

void sppsl_64(float *a, long n, float *b);

ARGUMENTS

* A (input): Cholesky factorization of the matrix A, as computed by SPPCO or SPPFA.
* N (input): Order of the matrix A. N >= 0.
* B (input/output): On entry, the right-hand side vector b. On exit, the solution vector x.
