I have problem running 17th row of this script, it says i need more input arguments....
Thrust,time_Rocket_Mass, are all constants.
I've tried Ft=int(ft) Ft=int(ft,t), But same problem occured
How can i integrate ft indefinitely???

There are a few crucial errs in your written code with integral. Here is a plain example how to embed integral in your code:
Th = 100;
RM = 300;
g = 9.81;
t0=0; tmax = 10;
ft = @(t)(Th./(t*RM)-g);
Ft = integral(ft, t0, tmax)

The integral function requires its first input to be a function handle. If you're trying to integrate a numeric set of data, see trapz or cumtrapz. If you're trying to integrate a symbolic expression use int instead.
