[petsc-users] Setting initial guess for KSP solver

[Jinquan Zhong]

Jed,

        PetscErrorCode  KSPSetInitialGuessNonzero(KSP ksp,PetscBool  flg)

does not provide the option to input x0 though.

Hi folks,

Is there a way to input my initial guess x0 into the KSP context before using KSPsolve() ?  I know exactly the initial guess x0 would be from other packages.  Do you have an example for that?

Thanks,

Jinquan
