SNESComputeFunction
Calls the function that has been set with SNESSetFunction().
Synopsis
#include "petscsnes.h"
int SNESComputeFunction(SNES snes,Vec x,Vec y)
Collective on SNES
Input Parameters
| snes | - the SNES context
|
| x | - input vector
|
Output Parameter
y -function vector, as set by SNESSetFunction()
Notes
SNESComputeFunction() is valid for SNES_NONLINEAR_EQUATIONS methods only.
Analogous routines for SNES_UNCONSTRAINED_MINIMIZATION methods are
SNESComputeMinimizationFunction() and SNESComputeGradient();
SNESComputeFunction() is typically used within nonlinear solvers
implementations, so most users would not generally call this routine
themselves.
Keywords
SNES, nonlinear, compute, function
