Variable Documentation

CSL_E

const csl::Expr CSL_E

inline

Initial value:

= csl::constant_s(
        "e",
        M_E,
        csl::ComplexProperty::Real)

CSL_INF

const csl::Expr CSL_INF

inline

Initial value:

= csl::constant_s(
        "INF",
        csl::ComplexProperty::Real)

Represents infinity in the program.

When an infinity appears in the abstract evaluation the program should return . is treated like a Variable. It is simply here to inform the user that *something bad happened** in the expr.

Bug:

Will not work for many cases, in particular log(0)!=. Not yet implemented.

CSL_PI

const csl::Expr CSL_PI

inline

Initial value:

= csl::constant_s(
        "\\pi",
        M_PI,
        csl::ComplexProperty::Real)

CSL_UNDEF

CSL_UNDEF

inline

Initial value:

= csl::constant_s(
        "CSL_UNDEF",
        csl::ComplexProperty::Real)

Constant that is useful in return of non-defined calculations as for example Commutator(): [A,B] returns CSL_UNDEF when it is not defined (more than AB-BA). It allows the program to avoid circular calculations and seg fault.
