(By Thomas Scofield)

\textrm{Given a (3d) spatial 1st order system initial value problem } \newline
\textrm{} \qquad\begin{array}{l} x' = f(t,x,y,z) \\
y' = g(t,x,y,z) \\ z' = h(t,x,y,z) \end{array},
\qquad (x_0, y_0, z_0) = (x(t_0), y(t_0), z(t_0)), \newline
\textrm{(} t \textrm{ is independent, }
x, y, z \textrm{ are dependent), this app plots the corresponding} \newline
\textrm{solution curves }
(x(t), y(t), z(t)) \textrm{ parametrically in phase space. For} \newline
\textrm{autonomous systems, an attempt is made to plot equilibria (red points).}
