The pseudocode for minimizing the *weighted* residual
by conjugate-direction method,
is effectively like that for the unweighted method
except that the initial residual is weighted
and the operator has the premultiplier .Naturally, the adjoint operator has the postmultiplier .In some applications the weighting operator is simply a weighting function or diagonal matrix
(so then )and in other applications, the weighting operator may be an operator,
like the derivative along a data recording trajectory
(so then ).
