        <description>Merge branch &apos;pr1819/jkruzik/feature-pcdeflation/master&apos; [PR #1819]* pr1819/jkruzik/feature-pcdeflation/master:PCDeflation.Implements multilevel deflation preconditioner that can shift part of the spectrum to a predefined value.Given a full rank deflation matrix W, the deflation preconditioner uses projections Q = W*(W&apos;*A*W)^{-1}*W&apos; and P = I - Q*A.It computes computes initial guess x0 = x_{-1} - Q*r_{-1} which is the solution on the deflation space.The preconditioner application consists of P*M^{-1} + factor*Q, where M^{-1} is an additional preconditioner.See the documentation for PCDEFLATION above PCCreate_Deflation for more detailed description.
