Document

Solve the cubic whose coefficients are in the eqn array and place the non-complex roots into the res array, returning the number of roots.

Usage

From source file:Cubic.java

protected int findRoots(double y, double[] roots) {
    double[] eqn = { p1.y - y, 3 * (p2.y - p1.y), 3 * (p1.y - 2 * p2.y + p3.y),
            3 * p2.y - p1.y + p4.y - 3 * p3.y };
    return CubicCurve2D.solveCubic(eqn, roots);
    // return solveCubic(eqn[3], eqn[2], eqn[1], eqn[0], roots);
}
