Computes the gradient that has been set with SNESSetGradient().
Synopsis
int SNESComputeGradient(SNES snes,Vec x, Vec y)
Collective on
SNES
Input Parameters
snes | - the SNES context

Output Parameter
y -gradient vector
Notes
SNESComputeGradient() is valid only
forSNES_UNCONSTRAINED_MINIMIZATION methods. An analogous routine
forSNES_NONLINEAR_EQUATIONS methods is SNESComputeFunction().
