Similarly, the documentation states
integral
A compatibility wrapper function that will choose between quadv and
quadgk depending on the integrand and options chosen.
oh, and that's apparently a doc typo. further down if you read the help for integral it states:
integral is a wrapper for quadcc (general scalar integrands), quadgk (integrals with specified integration paths), and quadv (array-valued integrands) that is intended to provide MATLAB compatibility.
I'll look back through and try a few things and open a bug once i refresh my memory with what's going on.
