int SNESGetLineSearchParams(SNES snes,double *alpha,double *maxstep,double *steptol)Not collective, but any processor will return the same values
snes | - The nonlinear context obtained from SNESCreate() | |
alpha | - The scalar such that x_{n+1} . x_{n+1} <= x_n . x_n - alpha |x_n . J . x_n| | |
maxstep | - The maximum norm of the update vector | |
steptol | - The minimum norm fraction of the original step after scaling |
