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. |
