Function documentation

WrappedMultiTF1(TF1 & f )

      constructor from a function pointer.

{ }

virtual ~WrappedMultiTF1()

      Destructor (no operations). Function pointer is not owned

{}

WrappedMultiTF1(const WrappedMultiTF1 & rhs)

      Copy constructor

{}

IMultiGenFunction * Clone()

 @name interface inherited from IFunction 

       Clone the wrapper but not the original function

unsigned int NDim()

 function dimension

const double * Parameters()

 @name interface inherited from IParamFunction 
 get the parameter values (return values cachen inside, those inside TF1 might be different)

void SetParameters(const double* p)

 set parameter values (only the cached one in this class,leave unchanges those of TF1)

unsigned int NPar()

 return number of parameters

std::string ParameterName(unsigned int i) const

 return parameter name (from TF1)

double DoEvalPar(const double* x, const double* p) const

 evaluate function passing coordinates x and vector of parameters
