often in my differentail equations class i took last semester we frequently evaluated 2nd order systems, they could easily be calculuted in MATLAB using pplane6, however pplane6 can only solve systems of 2nd order or less, because as its name says its a phase plane, meaning it can only evaluate the relationship between two variables simultaneously. Often in my dynamics class i find that I need to evaluate 3 states when working in three dimensions and always have to choose a numerical value for one of my variables and then evaluate the phase plane at that point, does anyone out there know of any software that can analyze and graphically interperet a 3rd order system of higher?

I know that what I am going to say to you is not going to like you too much. But if you want to learn more, write your own codec in Matlab. Your class companions will treat you with a lot of respect. :smile:

This is said by someone tired of searching Matlab programes in internet. I never found what I am looking for (Hey! it sounds to me as a U2 song).
 


There are several software options that can solve and graphically interpret 3rd order dynamical systems. Some popular choices include Maple, Mathematica, and MATLAB's Control System Toolbox. These programs have built-in functions and tools specifically designed for solving higher order systems of differential equations. Additionally, there are also online resources and tutorials available for using these software programs to solve 3rd order dynamical systems. It may also be helpful to consult with your professor or classmates for recommendations on which software would be best suited for your specific needs.
 
Thread 'Direction Fields and Isoclines'
I sketched the isoclines for $$ m=-1,0,1,2 $$. Since both $$ \frac{dy}{dx} $$ and $$ D_{y} \frac{dy}{dx} $$ are continuous on the square region R defined by $$ -4\leq x \leq 4, -4 \leq y \leq 4 $$ the existence and uniqueness theorem guarantees that if we pick a point in the interior that lies on an isocline there will be a unique differentiable function (solution) passing through that point. I understand that a solution exists but I unsure how to actually sketch it. For example, consider a...
