Method Details

solve

public Vector[] solve(Function f,
 Vector positions,
 Vector velocities,
 Vector masses,
 double h,
 double t)

this method calculates the positions and velocities of all celestial objects after every iteration using the explicit Euler method

Specified by:

solve in interface Solver

Parameters:

f - Function that is used to estimate the next step

positions - vector of all the positions

velocities - vector of all the velocities

masses - masses (used like this in the instances of this interface)

h - step-size

t - step we are currently on

Returns:

resulting Vector of the function
