partial derivative coding in matlab

Hi Guys,

I am having difficulty coding the attached equations into matlab. I was wondering if somebody could help code it for me.

[Walter Roberson]

Is this for numeric work such as ode45, or for symbolic work?

[Walter Roberson]

If you have the symbolic toolbox then I recommend using that to set up the equations. Follow the sequence of steps shown in the first example in the documentation for odeFunction

Though if you are doing partial derivatives you might need to use the PDE Toolbox, but not necessarily. https://www.mathworks.com/help/matlab/math/partial-differential-equations.html and https://www.mathworks.com/products/pde.html

Hi Walter,

It is for numeric. The parameters are defined in the pdf next to the equations

Answer 2

[Kamran Rahman]

Could show me how this would be done please.

Answer 3

Although I have not looked into details, you might be able to setup this problem using pdepe function available in base MATLAB (you don't need PDE Toolbox).
