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.
a
- coefficient of x^2b
- coefficient of x^1c
- coefficient of x^0
- 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.
a
- coefficient of x^4b
- coefficient of x^3c
- coefficient of x^2d
- coefficient of x^1e
- coefficient of x^0
- a sorted array of roots, or
null
if no solutions
exist
