MATLAB Creating Phase Portraits in MATLAB: Tips and Tricks for Linear Systems"

AI Thread Summary
MATLAB does not have built-in commands specifically for drawing phase portraits of linear systems, leading users to seek third-party tools, which may not be permissible in certain academic settings. The discussion highlights the need for alternative methods to visualize these systems. A suggested approach is to solve the ordinary differential equations (ODEs) and then plot the results. Additionally, there is a request for guidance on how to plot attractor and repeller basins, including the representation of arrows to indicate directionality in the phase portrait.

Hi

Doesn't MATLAB come with commands to draw phase portraits of linear systems? I can't seem to find anything in the help file. Google searches tell me about third party tools, which I am not supposed to use in my laboratory experiments and assignments.

Any ideas?

Thanks!

Is there any reason why you just can't solve the ODE and then plot the result?
 
Sorry, I should have actually asked the following question: how do I plot attractor/repellor basins (with arrows)?
