NAME

lis_solve_kernel - solve the linear equation with the predefined preconditioner

SYNOPSIS

#include "lis.h"

LIS_INT lis_solve_kernel(LIS_SOLVER solver);

DESCRIPTION

Solve the linear equation with the specified solver and the predefined preconditioner.

INPUT

A: The coefficient matrix
b: The right hand side vector
x: The initial vector
solver: The solver
precon: The preconditioner

OUTPUT

x: The solution
solver: The number of iterations, the execution time, etc.

EXIT STATUS

The following exit values are returned:

0: The process is normally terminated
unspecified: An error occurred

NOTE

See lis-($VERSION)/src/esolver/lis esolver ii.c, which computes the smallest eigenvalue by calling lis_solve_kernel multiple times, for example.
