finite Differences method in matlab
Hi
I need the code or information about solve the (finite differences method) in matlab for 3 equations

Post the equations

I'm not crazy, my mother had me tested.

Hi ammar;
I am not following that, what are you trying to do?
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: finite Differences method in matlab
That is probably a partial differential equation..

How to solve it or method of solution
How to sub equations in each other

Re: finite Differences method in matlab
Yes, it is a system of 3 partial differential equations but I do not know what Matlab commands are capable of doing it.

Re: finite Differences method in matlab
Do you know how to simplify these equations?

Re: finite Differences method in matlab
Hi;
Looks like it is a mixed difference and partial differential system of equations or is nabla displacement? Or is nabla, the backward difference operator.

Re: finite Differences method in matlab
I don't know I'll read some books about matlab and partial differential.
If you find anything please post it
thanks

Re: finite Differences method in matlab
I have looked around and if that is partials and a backward difference then I have never even worked on one.
