Class xlifepp::ARInterfaceCSVD

class ARInterfaceCSVD : public xlifepp::ARStdFrame<complex_t>

The ARInterfaceCSVD class handle complex data.

Given a complex matrix A and a complex vector x, this class defines the products: . (A*) * A * x and A * (A*) * x, for computation near the ends of the spectrum, . ((A*) * A - s * Id) * x and (A * (A*) - s * Id) * x, for computation near a real shift s.
