None of the integrators for functions are vectorized. So this would
always need a loop.

For lower precision, the integrators using samples have an axis
argument if you build an array for different values of the parameters
a and b.
Only cumtrapz (or using ode) can integrate for different limits simultaneously.

Which version to use depends on your requirements.
