Description
Function for evaluating polynomials using Horher's method.
- evaluatePolynomial :: (Vector v a, Num a) => a -> v a -> a
- evaluateEvenPolynomial :: (Vector v a, Num a) => a -> v a -> a
- evaluateOddPolynomial :: (Vector v a, Num a) => a -> v a -> a
- evaluatePolynomialL :: Num a => a -> [a] -> a
- evaluateEvenPolynomialL :: Num a => a -> [a] -> a
- evaluateOddPolynomialL :: Num a => a -> [a] -> a
Polynomials
Evaluate polynomial using Horner's method. Coefficients starts from lowest. In pseudocode:
evaluateOddPolynomial x [1,2,3] = 1 + 2*x + 3*x^2
Evaluate polynomial with only even powers using Horner's method. Coefficients starts from lowest. In pseudocode:
evaluateOddPolynomial x [1,2,3] = 1 + 2*x^2 + 3*x^4
Evaluate polynomial with only odd powers using Horner's method. Coefficients starts from lowest. In pseudocode:
evaluateOddPolynomial x [1,2,3] = 1*x + 2*x^3 + 3*x^5
