Function Documentation

geomspace()

std::vector< double > celeritas::geomspace	(	double	start,
		double	stop,
		size_type	n
	)

Return logarithmically spaced numbers over a given interval.

This is a geometric progression of values, where the ratio between each neighbor is constant.

logspace()

std::vector< double > celeritas::logspace ( double  start, double  stop, size_type  n  )

inline

Return logarithmically spaced numbers over a specific interval.
