Project documentation
The Physicists Hermite polynomial are defined as polynomials over ℤ in X recursively with physHermite 0 = 1 and physHermite (n + 1) = 2 • X * physHermite n - derivative (physHermite n). This polynomial will often be cast as a function ℝ → ℝ by evaluating the polynomial at X. -/ noncomputable def physHermite : ℕ → Polynomial ℤ | 0 => 1 | n + 1...
