Class LinearRoot

java.lang.Object

com.numericalmethod.suanshu.analysis.function.polynomial.root.LinearRoot

All Implemented Interfaces:

PolyRootSolver, java.io.Serializable

public class LinearRoot
extends java.lang.Object
implements PolyRootSolver

This is a solver for finding the roots of a linear equation. A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. That is, it has this form: ax + b = 0. The solution is simply

x = -b/a
