Method Detail

get

public Vec get(Vec p,
               double t,
               Vec v)

Given the state of the system p at time t, computes its first time derivatives and puts them in v, and returns v. The vector p is the position (p.x[0]) and speed (p.x[1]) of the charge moving along the z-axis , v.x[0] = p.x[1], and v.x[1] is the acceleration, and is computed from the coulomb force between the two charges.

Specified by:

get in class VecTimeField

Parameters:

p - the position (first location p.x[0]) and the speed (second location p.x[1]) of the moving charge.

t - the time

v - the derivative of the p vector--so v.x[0] is the speed and v.x[1] is the acceleration, as calculated using Coubomb's law for the force betweeen the charges.
