Detailed Description

Third-order forward-mode automatic-differentiation scalar.

v is the scalar value. d1, d2, and d3 are derivatives with respect to the path parameter s. Parametric path callbacks receive a seeded scalar (d1 = 1) and return or write one Jet3 per path dimension; COPP extracts all derivatives up to third order.

auto path = copp::Path::from_parametric(
    [](copp::Jet3 s) {
        return std::vector<copp::Jet3>{s, copp::sin(s), copp::powi(s, 3)};
    },
    0.0,
    1.0);
