case class Poly(c: VectorD, x: String = "x") extends Product with Serializable
The Poly class provides operations on univariate polynomials.
Poly (2, 3) => 3 x + 2
Note, reverse order of coefficients, i.e., coefficients for smallest terms first.
- c
the coefficients of the polynomial
- x
the variable/indeterminate of the polynomial
