Function documentation

double TFCS1DFunctionSpline::rnd_to_fct(double rnd) const virtual

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

void TFCS1DFunctionSpline::rnd_to_fct() const

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.

double TFCS1DFunctionSpline::rnd_to_fct() const pure virtual

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