Java Applets for Visualizing Vector Fields of ODEsBelow are useful applets for visualizing the vector fields of dynamical systems:Vector field of an ODE Phase plane of a 2D system Phase PortraitsA dynamical system can be modeled as a system of coupled differential equations u' = Au. The solutions to any such system are described by the eigenvalues and the eigenvectors of A Depending on the eigenvalues, the phase portrait of a 2dimensional system falls into one of the 10 classes in the handout below:Phase portraits of 2 dimensional dynamical systems
