36 \ingroup Hist
37The Formula Primitive class
38
39Helper class for TFormula to speed up TFormula evaluation
40TFormula can use all functions registered in the list of TFormulaPrimitives
41User can add new function to the list of primitives
42if FormulaPrimitive with given name is already defined new primitive is ignored
43
44Example:
45
46~~~ {.cpp}
47 TFormulaPrimitive::AddFormula(new TFormulaPrimitive("Pow2","Pow2",TFastFun::Pow2));
48 TF1 f1("f1","Pow2(x)");
49~~~
50
51 - TFormulaPrimitive is used to get direct acces to the function pointers
52 - GenFunc - pointers to the static function
53 - TFunc - pointers to the data member functions
54
55The following sufixes are currently used, to describe function arguments:
56
57 - G - generic layout - pointer to double (arguments), pointer to double (parameters)
58 - 10 - double
59 - 110 - double, double
60 - 1110 - double, double, double
