[petsc-users] Does KSPSetInitialGuessNonzero mean that x with initial values and will be updated?

[Brian Yang]

Hi all,

I am trying to solve Ax=0 with an initial values of x. I know
KSPSetInitialGuessNonzero is
able to disable the zero guess, so it will keep updating the initial x
right?

Thanks.
