When the solution takes the form typical of a classical oscillator. In the case of two ODEs, such a graph, the phase portrait of the system, is a curve on the phase plane and therefore is especially graphic.ĭamped Harmonic Oscillator Dynamics is described by the following system of equations:Īnd regardless of the initial conditions (x0, y0), comes to a state of equilibrium, point (0,0) with zero deflection angle and zero speed. In this case, the argument t enters the graphs only parametrically. The solutions of ordinary differential equations are often more convenient to represent not in the usual form, and in the phase space, along the axes of which the values of each of the found functions are plotted. This is the most extensive and supported package, providing tons of methods for solving diffura. ] add DifferentialEquations # an alternative way to add a package You also need a powerful tool for solving differential equations DifferentialEquations Not the most convenient option, but while we are waiting for the PlotlyJS update, you can try it for the sake of comparison. We drive in our REPL, JUNO or Jupyter notebook:
Vstack hstack lgadfly full version#
To begin with, download the Gadfly graphics package, and immediately the full version of the developer, so that it works well with our Julia 1.0.1. In short, we will solve diffura and build graphs. This is the most convenient tactic for mastering the instrument: in order to fill our hand, we will solve pressing problems, gradually increasing the complexity and finding ways to make our life easier. But to begin with, we need just the same purely narrow possibility of application - for solving typical problems of physics. We continue to master the young and promising general-purpose language Julia.
