KSPUnwindPreconditioner
Unwinds the preconditioning in the solution.
Synopsis
int KSPUnwindPreconditioner(KSP ksp,Vec vsoln,Vec vt1)
Collective on
KSP
Input Parameters
ksp | - iterative context
|
vsoln | - solution vector
|
vt1 | - temporary work vector
|
Output Parameter
vsoln -contains solution on output
Notes
If preconditioning either symmetrically or on the right, this routine
solvesfor the correction to the unpreconditioned problem. If preconditioning
onthe left, nothing is done.
