polyderivative (MathScript RT Module Function)
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.
