For example, f = 5, for 0<t<1, zero otherwise.
i tried the following code but it didn't work:
syms t
f = 10;
int(f)

syms t a b real
f = piecewise(0 < t & t < 1, 5, 0)
int(f, t, a, b)

Try this:
syms t
f = 0*t + 10;
int(f);
Cheers Manuel

you can't use piecewise in a numerical context. redefine your function as follows:
f = @(t) 5 .* (t > 0 & t < 1);
% then you can calculate numerical integral like this
integral(f, -1, 1)
Cheers
