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.
