Solving nonlinear diferential equations system

Hello everyone?

Could you help me to solve the differential equations below on matlab?

Note: pdot, qdot, rdot are derivatives of p,q and r respectively.

pdot = rdot + p*q - r*q ;
qdot = p*r - p^2 + r^2;
rdot = pdot - p*q - q*r ;

That's a system of coupled first-order ODEs. Have a look at the help and documentation for ode45, ode23.
