# polyderivative

Version:

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. MathScript encodes all polynomials as vectors in descending order.

## Syntax

polyderivative(a)
polyderivative(a, b)
c = polyderivative(a)
c = polyderivative(a, b)
[c, d] = polyderivative(a, b)
Legacy name: polyder

## a

Array of any dimension that represents a real or complex polynomial. If necessary, MathScript flattens the array a before the calculation.

## b

Array of any dimension that represents a real or complex polynomial. If necessary, MathScript flattens the array b before the calculation.

## c

Vector that represents a real or complex polynomial.

## d

Vector that represents a real or complex polynomial.

[C, D] = polyderivative([1], [1, 1, 1])
