What exactly are you having issues with?

algorithm of runge kutta method for coupled equations.

runge kutta method algorithm to write the matlab code to solve the coupled non linear differential equations (bounder layer problems).

are you seeking for a book or someone to help you to teach how to code? I wouldn't mind helping :if I can: but from the way you ask, I feel that you don't have much clue about what you are talking about. I find it a bit selfish to expect someone to pop out and teach you everything one by one. makes me think like someone is trying to get the homework done.

You can have a look at Leveque's book, I 've been told that it was a good one, and its easy to understand.

Are you having issues with the Runge Kutta algorithm methodology, or the coding aspect? Which Runge Kutta method are you trying to use?

Here is an example of a generic RK4 method already available if you would have simply googled 'matlab runge kutta'.
