Detailed Description

Definition at line 38 of file Enge.h.

Constructor & Destructor Documentation

endfieldmodel::Enge::Enge ( )

inline

Default constructor

Definition at line 41 of file Enge.h.

References SetEngeDiffIndices().

Here is the call graph for this function:

endfieldmodel::Enge::Enge	(	const std::vector< double >	a,
		double	x0,
		double	lambda,
		int	max_index
	)

inline

Builds Enge function with parameters a_0, a_1, ..., lambda and x0.

max_index is the maximum derivative that will be used in calculation if, after setup, you find you need to calculate higher derivatives, you can just call SetEngeDiffIndices(n) where n is the highest derivative you think you will need.
