Class xlifepp::ARGenToStdShf

template<class TA_, class TB_>
class ARGenToStdShf : public xlifepp::ARStdFrame<TA_>

Class used to transform a generalized problem into a standard one.

B is supposed to be invertible. Shift mode case. Matrix-vector product provided: y <- inv(inv(B)*A-sigma*Id)*x sigma has the type of A

Destructor.

virtual void MultOPx(TA_ *x, TA_ *y)
