Dear Thomas,
Unfortunately, I do not know if any packages implement this functionality.
Though, it is a topic that interests me.
Unlike the "classic discriminant", I prefer to work with the reduced
polynomial. This "discriminant" is generalizable to a superset of Chebysev
polynomials (which I
Colleagues
Given the coefficients of a cubic polynomial, a,b,c,d and
using
discriminant_cubic <- function(a, b, c, d) {
D <- 18 * a * b * c * d - 4 * b^3 * d + b^2 * c^2 - 4 * a * c^2 - 27 * a^2
* d^2
return(D)
}
I can find the discriminant of a cubic polynomial.
Is there an R package which
