First, what integral do you want to do? Line integral? Flux?
Once you know you can write the components of the integrand and use
any of the *quad functions.
However, GNU Octave is meant for numerical calculations. If what you
want is symbolic calculations then you better try other softaware (or
ask if the symbolic package for GNU Octave works already), for example
Maxima.
