◆ RecursionRelation() [1/3]

polynomial::RecursionRelation::RecursionRelation ( )

Default constructor, initialises identity operator.

Definition at line 36 of file RecursionRelation.cpp.

References operator_m, and polynomial::DifferentialOperator::setPolynomial().

Here is the call graph for this function:

◆ RecursionRelation() [2/3]

polynomial::RecursionRelation::RecursionRelation	(	const std::size_t &	power,
		const std::size_t &	highestXorder
	)

Constructor, initialises the operator.

\begin{eqnarray*} { \Big(\frac{1}{\rho(1 + x/\rho)}\frac{\partial}{\partial x} + \frac{\partial^2}{\partial x^2} + \frac{1}{(1 + x/\rho)^2}\frac{\partial^2}{\partial s^2}\Big)^n \end{eqnarray*}

highestXorder is the highest power of x

Parameters

power	-> Number of times the differential operator is applied
highestXorder	-> Highest order of x before truncation
