Sir how can we add equations for skin fraction and Nustle number in the code and how can we extract table of values for factors affecting skin friction and Nustle number
Sir can u please explain how to write the code when the concentration second derivative (Phi-second derivative) is existing in temperature equation . when I have Dufour parameter I have concentration second derivative in temp
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.
Sir please give me your mail id. I will try this problem with your suggestion. Suppose if I fail to achieve the solution, I will share my code to your mail
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?
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 ?
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.
@@muhammadasiffarooqphd Thank yoo so much sir, i have another question, if we have some funtion in boundary conditioon for example we have f=sinx then how will we add such things in the boundary conditions?
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.
Salam respected sir please guide me about the error . Error using bvp4c (line 251) Unable to solve the collocation equations -- a singular Jacobian encountered. Error in ANN (line 22) sol=bvp4c(@bvp2D,@bc2D,solit);

wow thank you @ please how work this by finite element method, how insert stream line
Sir, in thin needle problem ode contains eta, how to write the code, please reply me sir. Thank you sir.
How many equations do you have?
Continuity equation, momentum equation and energy equations

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.

@@muhammadasiffarooqphd bvp4c can't handle it?
Also i tried to run the script given in description, it says bvp2D is undefined, how to debug this error?
Can you share command for plotting stream function graph in MATLAB using BVP4C.
I will be extremely grateful.
Kindly explain nusselt no and Cf in this code
Nusselt number measures heat transfer rate from the surface. Cf measures skin friction coefficient on the surface.
Code is not running the program sir
The same code I shared? Or your code?
Sir do a video in 3 system of bvp... Not only the diagram.. Need the solution...
Sir, In this bvp4c code, can we plot the streamline plot? Is there any command we can use?.
Yes you can do it. Please use fluid mechanics concept for streamlines.

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

In N U and Cf that does 4 represent after comma
Please write Nu and Cf formula in comment.
I need to plot these two Cf and Nu no
And u wrote Nu= vpa(-y(5,1),4) what does 4 represent in parentheses
