Constructor & Destructor Documentation

lux::IrregularFunction1D::IrregularFunction1D	(	float *	aX,
		float *	aFx,
		int	aN
	)			[inline]

Creates a 1D function from the given data. It is assumed that the given x values are ordered, starting with the smallest value. The function value is clamped at the edges. It is assumed there are no duplicate sample locations.

Parameters:

	aX	The sample locations of the function.
	aFx	The values of the function.
	aN	The number of samples.
