How to solve simultaneous non-linear differential equations in MATLAB m-file without using the commands?. can you give me the program?.

"without using the commands"?

Matlab is -from a practical point of view- scripts based. You only need a few lines of code in order to solve a PDE, but you do need to write those lines; there is no "generic" program.
Matlab is quite different from e.g. Mathematica

Look up the command Ode45, that should be a good starting point.

Edit: And this thread should not be in the EE forum.
