Functions
double	GOAT::maths::abs (std::complex< double > x)
	absolute value of the complex valued variable x
double	GOAT::maths::findmax (std::vector< double > d, std::size_t &index)
	finds maximum in data This function finds the maximal value inside a vector
std::size_t	GOAT::maths::FWHM (std::vector< double > d, std::size_t index)
	estimates the full width at half maximum of a peak around at the position inside a vector The function gives back the full width at half maximum (FWHM) by finding the first point with less than (or equal to) the half of the maximal value left and right from position index inside the vector d
double	GOAT::maths::mean (std::vector< double > d)
	Calculates the mean of the data stored in d.
std::vector< double >	GOAT::maths::movingAvg (std::vector< double > d, int n)
	calculates the moving average of the data Calculates the (unweighted) moving average over the data stored in d. The average will be calculated over n elements
double	GOAT::maths::newton_root (std::function< double(double)> f, std::function< double(double)> df, double x0=0, double eps=std::numeric_limits< double >::min())
double	GOAT::maths::sqr (double x)
	square of x
bool	GOAT::maths::testnan (double x)
	tests x on NaN
std::string	GOAT::maths::tl (std::string)
	Converts string into lowercase This function converts all characters in a string into lower case.
