cheb_find_max: Routine to find maximum values of a curve

In sebaki/ChebyshevMax: Curve Fitting and Extreme Value Search with Chebyshev Polynomials

Description

cheb_find_max fits a Chebyshev polynomial of order n to a data series using the method of least squares, locates the extrema of the fit using the Newton-Raphson-algorithm of the first derivation and checks for maxima using the second derivative.

Usage

cheb_find_max(d, x_axis, n, maxima_bound_lower = NA,
  maxima_bound_upper = NA)

Arguments

d	Data series to be fitted
x_axis	Arbitrary x-axis
n	Order of the polynomial
maxima_bound_lower	Lower boundary of the maximum value search
maxima_bound_upper	Upper boundary of the maximum value search

Value

list of calculated parameters like Chebyshev coefficients, values of the filtered model, values of the first and seconda derivation, postitions and values of maxima
