polyder
Derivative of a polynomial.
Syntax
q = polyder(p)
q = polyder(a,b)
[n,d] = polyder(a,b)
Inputs
- p
- The coefficients of the polynomial to differentiate.
- a,b
- The coefficients of a polynomial product (a*b) or quotient (a/b) to differentiate, depending on the outputs specified.
Outputs
- q
- The coefficients of the polynomial derivative.
- n,d
- The coefficients of the polynomial derivative, expressed as a ratio (n/d) when the input is a polynomial quotient.
Example
Derivative of a single polynomial, 2x^4 + 3x^3 + 3x^2 + 2x + 1.
q = polyder([2,3,3,2,1])q = [Matrix] 1 x 4
