Function Documentation

Whittaker() [1/2]

const std::vector< double > sablib::Whittaker	(	const std::vector< double > &	y,
		const double	lambda,
		const unsigned int	s = 2 )

Performs Whittaker smoothing (std::vector<double> version, without weights).

Parameters

y	The input data to be smoothed.
lambda	Smoothing parameter (larger values lead to more smoothing, but may flatten peaks).
s	The order of the difference (usually s = 1, 2, or 3).

Returns

The smoothed data.

Whittaker() [2/2]

const std::vector< double > sablib::Whittaker	(	const std::vector< double > &	y,
		const std::vector< double > &	w,
		const double	lambda,
		const unsigned int	s = 2 )

Performs Whittaker smoothing (std::vector<double> version, with weights).

Parameters

y	The input data to be smoothed.
w	Weights for each data point.
lambda	Smoothing parameter (larger values lead to more smoothing, but may flatten peaks).
s	The order of the difference (usually s = 1, 2, or 3).

Returns

The smoothed data.

Exceptions

std::invalid_argument

One or more parameters wrong.
