Homework Help: Plotting vector fields in MATLAB or Maple

  1. Dec 11, 2008 #1
    1. The problem statement, all variables and given/known data

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

    2. Relevant equations
    3. 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.
