static int DiCurveFitting< T1, T2 >::calculateCoefficients	(	const T1 *	x,
		const T2 *	y,
		const unsigned int	n,
		const unsigned int	o,
		T3_ *	c
	)			[inline, static]

calculate coefficients for resulting polynomial function.

T1 = type of x coordinates T2 = type of y coordinates T3_ = type of coefficients (and for internal calculations)

Parameters:

	x	array with x coordinates of given points
	y	array with y coordinates of given points
	n	number of entries in array (= points)
	o	order of polynomial function
	c	array to store the resulting coefficients (o+1 entries !)

Returns:

true if successful, false otherwise

		const T1	xe,
		T2 *	y,
		const unsigned int	n,
		const unsigned int	o,
		const T3_ *	c
	)			[inline, static]

calculate y coordinates for the given range of x coordinates.

The polynomial function is defined by the specified coefficients. T1 = type of x coordinates T2 = type of y coordinates T3_ = type of coefficients (and for internal calculations)

Parameters:

	xs	first x coordinate for computation
	xe	last x coordinate for computation
	y	array to store the resulting y coordinates (n entries !)
	n	number of entries in array (= points)
	o	order of polynomial function
	c	array of coefficients computed by the above method (o+1 entries !)

Returns:

true if successful, false otherwise
