[petsc-users] Linesearch algorithm

[behzad baghapour]

Dear Developers,

I wish to know when the algorithm of Linesearch used by SNESLineSearchCubic
or SNESLineSearchQuadratic calls the Jacobian calculation routine defined
by user? Is it a way to change the Jacobian before calling the line-search
routines?

Thanks,
BehZad
