POLY

 

The POLY function returns the results of the input variables and coefficients evaluated in a polynomial function.

 

Format

 

Arguments definition

The input variable for the defined polynomial function

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

The starting point of the polynomial function

The set of polynomial coefficients (up to 31)

 

Formulation

 

Example

POLY (time, 0, 1,1,1)

•     x = time: Independent variable

•     x0= 0: Shift in the polynomial

•     a0, a1, a2: Define coefficient for the polynomial series

•    a0 = 1, a1 = 1, a2 = 1
