MATLAB Plotting vector fields in MATLAB or Maple

[JefeNorte]

Homework Statement

The original problem was x'=(-2 1; 1 -2)*x and I needed to find two linearly independent solutions.

Homework Equations

The Attempt at a Solution

I found that x1=(1;1)e^(-t) and x2=(1;-1)e^(-3t). Now I am trying to plot a vector field of this. Is there an easy way to do this using MATLAB or Maple or do i need to do each point by hand? I would like to avoid unnecessary headaches if possible.

Thanks

There are many good tutorials on Matlab plotting on YouTube. Here is one related to vector field plotting.
