    • solveQuadric

      public static final double[] solveQuadric(double a, double b, double c)
      Solves the equation ax^2+bx+c=0. Solutions are returned in a sorted array if they exist.
      Parameters:
      a - coefficient of x^2
      b - coefficient of x^1
      c - coefficient of x^0
      Returns:
      an array containing the two real roots, or null if no real solutions exist

    • solveQuartic

      public static double[] solveQuartic(double a, double b, double c, double d, double e)
      Solve a quartic equation of the form ax^4+bx^3+cx^2+cx^1+d=0. The roots are returned in a sorted array of doubles in increasing order.
      Parameters:
      a - coefficient of x^4
      b - coefficient of x^3
      c - coefficient of x^2
      d - coefficient of x^1
      e - coefficient of x^0
