How to compute an indefinite integral?

I am trying to have MATLAB solve

2,241.1 = integral (from 0 to t) of (1000dt).

For whatever reason, I cannot get the integral to work even if I take out the solve and such.

syms x t

int(1000, [0,t])

returns the following error:

??? Error using ==> mupadmex Error in MuPAD command: Second argument must be either of form x or x=a..b [int]

Error in ==> sym.int at 40 r = mupadmex('symobj::intindef',f.s,x.s);

Error in ==> Kocis_hw1_problem4 at 54 int(1000,[0,t])

Can anyone tell me how to do this?

Thanks, Tiffany

>> int(1000,t,0,t)

The limits go in as the 3rd and the 4th arguments seperately:

That worked! but the link says this:

int(expr,var,[a,b]), int(expr,var,[a b]), and int(expr,var,[a;b]) are equivalent to int(expr,var,a,b).

Whats the difference?

This feature was added in MATLAB R2013b:
