Planar vector fields is a small, simple, java based application specially designed to help you plot planar vector fields. A vector field on is a function that assigns to each point a threedimensional vector. That may not make a lot of sense, but most people do know what a vector field is, or at least theyve seen a sketch of a vector field. This is kind of common practice when vector fields are drawn or when some kind of software is drawing them for you so there are ways of getting around this one way is to just use colors with your vectors so ill switch over to a different vector field. You can also plot a vector field from a list of vectors as opposed to a mapping. A mappoint vector is a container object that holds planar point coordinates and attributes. Here, we introduce this subject and formalize the terminology about nontrivially recurrent points and nonwandering points for the context of planar piecewise smooth vector fields. Since graphing the flow lines of a planar vector field is equivalent to drawing the phase portrait of this same autonomous system, there is also a related vector fields task.
