Function documentation

template<typename Txvec, typename Ty, typename Trandom>
auto TFCS1DFunctionTemplateHistogram<Txvec, Ty, Trandom>::MemorySize() const -> std::size_t override

Gives the total memory size, including the size of additional memory allocated inside the class

template<typename Txvec, typename Ty, typename Trandom>
void TFCS1DFunctionTemplateHistogram<Txvec, Ty, Trandom>::Initialize(const TH1* hist, bool doprint = true)

Initialize from root histogram. Depending on the precision of the x- and y-axis, bins are merged if numerical identical

template<typename Txvec, typename Ty, typename Trandom>
auto TFCS1DFunctionTemplateHistogram<Txvec, Ty, Trandom>::rnd_to_fct(double rnd) const -> double override

Function gets random number rnd in the range [0,1) as argument and returns function value according to a histogram distribution

template<typename Txvec, typename Ty, typename Trandom>
void TFCS1DFunctionTemplateHistogram<Txvec, Ty, Trandom>::rnd_to_fct() const override

Function gets array of random numbers rnd[] in the range [0,1) as arguments and returns function value in array value. For a n-dimensional function, value and rnd should both have n elements.

template<typename Txvec, typename Ty, typename Trandom>
auto TFCS1DFunctionTemplateHistogram<Txvec, Ty, Trandom>::rnd_to_fct() const -> double pure virtual

Function gets random number rnd in the range [0,1) as argument and returns function value
