      Thank you for your question. To solve this problem, take the second derivative of the temperature equation and substitute that equation into the concentration equation. If you have any questions, please let me know.

    Aoa Sir, how can i define more than one legend in matlab? i tried to but it gives error "ignoring extra legends" and show only one in figure. How can i resolve this issue?

      WS, it is possible to define two legends. But the code is complicated. But I suggest you to use textbox for your other information. It is easier.

    Aoa Sir, thank you for sharing the knowledge. i am wondering what is the 3rd argument in linspace? you explained 0 and 20 but what is the function of 25 ?

    • @muhammadasiffarooqphd
      @muhammadasiffarooqphd  Рік тому +2

      WS, thank you very much. The third argument gives number of points. For example linspace makes 25 points starting from 0 and end at 20. Please follow my MATLAB course I started recently on my channel. I will explain later all these commands in the MATLAB Programming course.

    Sir I am trying to solve stability analysis for the smallest eigenvalue in the bvp4c solution of coupled ODE. Still, I am not getting any idea about how to make stability analysis code in bvp4c. I am getting data using bvp4c for coupled ODE but not getting an idea about stability. So, I request you kindly help with that.

      Hello, bvp4c gives solution of single or coupled ODEs. To find eigenvalues you can use eig command.
