Class MEAL::CongruenceTransformation
-
class CongruenceTransformation : public MEAL::Transformation<Complex2>
A congruence transformation, \(\rho^\prime=J\rho J^\dagger\).
This class models the transformation of the matrix, \( \rho \) by a congruence transformation in \( J \). The partial derivatives of the output, \( \rho^\prime \), are computed using the product rule and the partial derivatives of \( \rho \) and \( J \).
