BaselineGoldindec()

const std::vector< double > sablib::BaselineGoldindec	(	const std::vector< double > &	y,
		const unsigned int	polyorder,
		const double	peak_ratio = 0.5,
		const double	alpha = 0.99 *0.5,
		const unsigned int	loop = 100,
		const double	eps = 1.0e-4,
		const unsigned int	loop_legend = 50,
		const double	eps_legend = 1e-3,
		const double	eps_s = 1e-4 )

Performs baseline estimation using the Goldindec algorithm.

Parameters

y	The input data vector (signal to be processed).
polyorder	The order of the polynomial to be fitted.
peak_ratio	Estimated ratio related to the peak content (default: 0.5).
alpha	A weighting parameter for the iterative process (default: 0.99 * 0.5).
loop	Maximum number of iterations for the main loop (default: 100).
eps	Convergence threshold for the main loop (default: 1.0e-4).
loop_legend	Maximum number of iterations for internal LEGEND algorithm (default: 50).
eps_legend	Convergence threshold for internal LEGEND algorithm (default: 1e-3).
eps_s	Convergence threshold for the internal parameter s (default: 1e-4).

Returns

A vector of the same size as y containing the estimated baseline.

Exceptions

std::invalid_argument

One or more parameters are wrong.
