SNESComputeMinimizationFunction
Computes the function that has been set with SNESSetMinimizationFunction().
Synopsis
#include "petscsnes.h"
int SNESComputeMinimizationFunction(SNES snes,Vec x,PetscReal *y)
Collective on SNES
Input Parameters
| snes | - the SNES context
|
| x | - input vector
|
Output Parameter
y -function value
Notes
SNESComputeMinimizationFunction() is valid only for
SNES_UNCONSTRAINED_MINIMIZATION methods. An analogous routine for
SNES_NONLINEAR_EQUATIONS methods is SNESComputeFunction().
SNESComputeMinimizationFunction() is typically used within minimization
implementations, so most users would not generally call this routine
themselves.
Keywords
