RandStudentT

Class defining methods for shooting Student's t- distributed random values, given a number of degrees of freedom a (default=1.0). Default values are used for operator()().

Valid input values are a > 0. When invalid values are presented, the code silently returns HUGE_VAL from <math.h> which is the same as MAXDOUBLE in <values.h> on systems where the latter exists.

Constructors

inline RandStudentT(HepRandomEngine& anEngine, HepDouble a=1.0)

inline RandStudentT(HepRandomEngine* anEngine, HepDouble a=1.0)

These constructors should be used to instantiate a RandStudentT distribution object defining a local engine for it.

The static generator will be skipped using the non-static methods defined below.

If the engine is passed by pointer the corresponding engine object will be deleted by the RandStudentT destructor.

If the engine is passed by reference the corresponding engine object will not be deleted by the RandStudentT destructor.

Destructor

virtual ~RandStudentT()

()

HepDouble operator()()

HepDouble operator()(HepDouble a)

Methods using the localEngine to shoot random values, by-passing the static generator.

fire

inline HepDouble fire()

HepDouble fire(HepDouble a)

Methods using the localEngine to shoot random values, by-passing the static generator.

fireArray

void fireArray(const HepInt size, HepDouble* vect)

void fireArray(const HepInt size, HepDouble* vect, HepDouble a)

Methods using the localEngine to shoot random values, by-passing the static generator.

Static methods to shoot random values using the static generator

static inline HepDouble shoot(HepRandomEngine* anEngine)

static HepDouble shoot(HepRandomEngine* anEngine, HepDouble a)

Static methods to shoot random values using a given engine by-passing the static generator.

shootArray
