Function Documentation

gsl_interpolate() [1/2]

template<typename realT>

int mx::math::gsl_interpolate	(	const gsl_interp_type *	interpT,
		realT *	xin,
		realT *	yin,
		size_t	Nin,
		realT *	xout,
		realT *	yout,
		size_t	Nout )

Interpolate a 1-D data X vs Y discrete function onto a new X axis.

Parameters

	interpT	one of the gsl interpolation types.
[in]	xin	the input x-axis
[in]	yin	the input y-values
[in]	Nin	the size of the input x-y data series
[in]	xout	the desired x-axis
[out]	yout	the output interpolated y-values, pre-allocated
[in]	Nout	the size of the output x-y axis

Returns

0 on success

-1 on a gsl error.

gsl_interpolate() [2/2]

template<typename realT>

int mx::math::gsl_interpolate	(	const gsl_interp_type *	interpT,
		std::vector< realT > &	xin,
		std::vector< realT > &	yin,
		std::vector< realT > &	xout,
		std::vector< realT > &	yout )

Interpolate a 1-D data X vs Y discrete function onto a new X axis (vector version).

Parameters

	interpT	of the gsl interpolation types.
[in]	xin	the input x-axis
[in]	yin	the input y-values
[in]	xout	the desired x-axis
[out]	yout	the output interpolated y-values, does not need to be allocated

Returns

0 on success or -1 if GSL reports an interpolation error.
