C#
public static BarycentricSeries GetChebyshevInterpolator(
	Func<double, double> function,
	double lowerBound,
	double upperBound,
	int degree
)

Parameters

function  Func<Double, Double>
A delegate that represents the function to interpolate.
lowerBound  Double
The lower bound of the interval.
upperBound  Double
The upper bound of the interval.
degree  Int32
The desired degree of the interpolating polynomial.

Return Value

BarycentricSeries
A BarycentricSeries that interpolates function over the interval from lowerBound to upperBound through the Chebyshev points of the second kind of degree degree.

Exceptions

ArgumentExceptionThe interval has zero length.
ArgumentNullExceptionfunction is null.
ArgumentOutOfRangeExceptiondegree is less than zero.
