RealOperatorChebyshevSeries

Base class: Operator

A RealOperatorChebyshevSeries defined by applying a scalar-valued Chebyshev series to an operator. For example, a series p(x) = sum_n a_n T_n(x) becomes p(A) = sum_n a_n T_n(A) when applied to an operator A.

Constructors​

RealOperatorChebyshevSeries(const Operator operator, const RealChebyshevSeries series) -> RealOperatorChebyshevSeries​

Constructs a RealOperatorChebyshevSeries from an Operator and a ChebyshevSeries.

Parameters​

  • operator: The operator to wrap (e.g. X, Create, operator_sum).
  • series: The Chebyshev series to apply to the operator.
