PetscErrorCode PCApplyBAorABTranspose(PC pc, PCSide side, Vec x, Vec y, Vec work)
Collective
Input Parameters#
pc - the
PC
preconditioner contextside - indicates the preconditioner side, one of
PC_LEFT
,PC_RIGHT
, orPC_SYMMETRIC
x - input vector
work - work vector
Output Parameter#
y - output vector
Note#
This routine is used internally so that the same Krylov code can be used to solve and , with a preconditioner defined by . This is why this has the funny form that it computes
