int SNESQuadraticLineSearch(SNES snes, Vec x, Vec f, Vec g, Vec y, Vec w,
double fnorm, double *ynorm, double *gnorm,int *flag)
Collective on SNES and
Vec
| snes | - the SNES context |
| x | - current iterate |
| f | - residual evaluated at x |
| y | - search direction (contains new iterate on output) |
| w | - work vector |
| fnorm | - 2-norm of f |
| g | - residual evaluated at new iterate y |
| y | - new iterate (contains search direction on input) |
| gnorm | - 2-norm of g |
| ynorm | - 2-norm of search length |
| flag | - 0 if line search succeeds; -1 on failure. |
