OperatorPolynomial

A polynomial operator is defined in terms of a polynomial and an operator. It applies the polynomial to the operator when acting on vectors. For example, a polynomial $p(x) = \sum_{n=0}^{N} a_n x^n$ becomes $p(A) = \sum_{n=0}^{N} a_n A^n$ when applied to an operator $A$.

Constructors

OperatorPolynomial(const Operator operator, const Polynomial<real> polynomial) -> OperatorPolynomial

Constructs an OperatorPolynomial from an Operator and a Polynomial.

Parameters

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