title: Generate bifurcation diagram for 2D system
body: <p>Drawing bifurcation diagram for 1D system is clear but if I have 2D system on the following form
                <code>dx/dt=f(x,y,r),
                 dy/dt=g(x,y,r)</code></p>
  
  <p>And I want to generate a bifurcation diagram in MATLAB for x versus r.
  What is the main idea to do that or any hints which could help me?</p>
