Method Detail

• 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

  Returns:

  a sorted array of roots, or null if no solutions exist
