@@MAFarooqi hellow its not showing the phase portrait diagram while I said proceed. it only puts the dimention of x and y but not the solution. why can you show me please
@@tekalignmohammed1647 Is it showing some small arrows? if yes, click somewhere near these arrows to indicate the initial conditions and it will sketch the phase portrait corresponding to that initial condition.
Phase portrait technique to analyze nonlinear systems is basically valid for second order system. It is because plotting graphs in three dimensional space becomes quite difficult, and in higher dimensions, it may not be possible. However, if you still need to plot the phase portraits for your fourth order system, I would recommend you implement the system in Simulink and obtain image (shadow) of phase portraits in two dimensional space.
@@mathematics.lovers79 I have mentioned the procedure to draw the phase portraits in my previous post. Implement the system in Simulink and then use XY plotter and obtain a plot of x1 vs x2, x1 vs x3, x1 vs x4 and similarly other combinations. If you still face any difficulty, please let me know.

Well explained.........Good Job, please keep posting such a videos
Great Job thank you very much,it is very useful
Thanks.
Much informative sir ...
Thank you for efforts...
Welcome
@MAFarooqi Sir, it is not working for the version of MATLAB 2023. I was trying to use pplane9 and pplane8, but some errors occurred. Please help me
السلام عليكم، what is name of this tool box for simulation in matlab?
It is pplane8.m, you can run it in MATLAB.
do you have Sir program for plotting prey predator model in 3 -dim for nonlinear system
Perfect (Y)
Assalamualaikum sir, can you tell or explain how to get waveforms of trajectories in pplane9??
PPlane is not working with some later versions of MATLAB.
Thank your Sir for thé vidéo, Sir how to plot phase portrait of a planar differential system in Poincaré disc?
I am really sorry that I have no knowledge of Poincare disc. If I get time, I shall try to look into this topic.
@@MAFarooqi thank you Sir.
👍🏼👏🏻
can you put the code here??
The code for ppalne8 can be downloaded from the following link.

@@MAFarooqi No sir its not showing any thing
Salam sir
Kindly tell me that how to draw phase portrait for system of 4 non-linear coupled ODEs thanx pls reply

@@MAFarooqi sir u mean that i have to draw it for a pairs of 2 Equations sepratly in PPlane?
@@MAFarooqi sir i am sharing one of my ODE i-e dx/dt = −k1x + (k−1 − k3x)y + k−3z here x,y,z are variables
