Owning Class: polynomials

Requires: MathScript RT Module

Syntax

polyderivative(a)

polyderivative(a, b)

c = polyderivative(a)

c = polyderivative(a, b)

[c, d] = polyderivative(a, b)

Legacy Name: polyder

Description

Generates the symbolic derivative of a polynomial or rational polynomial. If you do not request an output or if you request only one output, polyderivative(a) is the derivative of polynomial a, and polyderivative(a, b) is the derivative of polynomial a*b. If you request two outputs, c is the numerator and d is the denominator of the derivative of the rational polynomial a / b. LabVIEW encodes all polynomials as vectors in descending order.

Examples

Inputs

a Specifies a vector that represents a real or complex polynomial.
b Specifies a vector that represents a real or complex polynomial.

Outputs

Name Description
c Returns a vector that represents a real or complex polynomial.
d Returns a vector that represents a real or complex polynomial.
