I would like to integrate a multivariate function such as
over . Is there a built in function in matlab to do this? Expanding it to a function of , the components of x will be really tedious if the dimension is higher.

Have a look at the help and documentation for integral2. That should be the function to do 2-D integrals, that sounds like the function you're looking for.

That is because your function is array-valued, and as far as I know integral2 doesn't handle that. You might have to evaluate the integral for each component separately.
