Function Documentation

logspace()

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

Return logarithmically spaced numbers over a given interval.

Unlike numpy's logspace which assumes the start and stop are log-10 values (unless given another argument), the start and stop are the actual first and last values of the resulting vector.
