SNESComputeFunction#
Calls the function that has been set with SNESSetFunction().
Synopsis#
#include "petscsnes.h"
PetscErrorCode SNESComputeFunction(SNES snes, Vec x, Vec y)
Collective
Input Parameters#
snes - the
SNEScontextx - input vector
Output Parameter#
y - function vector, as set by
SNESSetFunction()
Notes#
SNESComputeFunction() is typically used within nonlinear solvers
implementations, so users would not generally call this routine themselves.
When solving for \(F(x) = b\), this routine computes \(y = F(x) - b\).
