Namespace: Altaxo.Calc
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public static double[] ChebychevPolynomialFirstKind(
	int degree,
	double intervalBegin = -1,
	double intervalEnd = 1
)

Parameters

degree  Int32
The polynomial order and therefore the number of roots.
intervalBegin  Double  (Optional)
The real domain interval begin where to start sampling.
intervalEnd  Double  (Optional)
The real domain interval end where to stop sampling.

Return Value

Double
Samples in [a,b] at (b+a)/2+(b-1)/2*cos(pi*(2i-1)/(2n))
