inlinestatic

\( \psi_{mod} := \begin{cases} H(\psi_p(R,Z))\text{ for } P(R,Z) \\ \psi_p(R,Z) \text { else } \end{cases} \)

where H is the integrated dg::IPolynomialHeaviside function and P is a predicate that returns either true or false.

Note: the predicate can usually be true everywhere, the idea for the predicate is to be able to selectively target the private flux region(s) for modification.; This is a helper function used in the implementation of dg::geo::createModifiedField

Parameters

predicate	P(R,Z) indicates the positions where Psi is to be modified (true) or not (false)
psip	the flux function to be modified
psi0	parameter for dg::PolynomialHeaviside function
alpha	parameter for dg::PolynomialHeaviside function
sign	parameter for dg::PolynomialHeaviside function
