CHEBY

 

The CHEBY function returns the result of the coefficients and variables evaluated using the Chebyshev polynomial.

 

Format

 

Arguments definition

The input variable for the Chebyshev equation

•     Generally, this variable is a real number, function, or time.

The x-direction offset for the variable () in the Chebyshev polynomial

The coefficient values in the Chebyshev polynomial that calculate the linear superposition in line with the Chebyshev polynomial

•     These values are defined by the number of input coefficients and can include up to 31 coefficients.

 

Formulation

 

Example

CHEBY (time, 1, 1, 1, 1)

•     x = time: Independent variable

•     x0 = 1: Shift in the Chebyshev polynomial

•     c0,  c1, c2 : Define coefficient for the Chebyshev polynomial

•    c0 = 1, c1 = 1, c2 = 1
