> i hav solved the problem by solving the entire equation of x(t) which involves integral and non integral terms.since the length of the solution became huge so i was trying to find a shorter way...i hav seen the ode45 command but didnt used it ...i will definitely try to solve the state equation using it...thanks 4 d help.......................ROHIT
