page 18 of the scipy tutorial sheds more light on this. I don't think the output has to be scalar.
... gradually getting there!

Yes, I think it is doing exactly what Matlab would do. You can have a
vector input, you just need to have a scalar output that you are trying
to drive to zero.

In matlab, one would define a vector function say myfunc returning a vector F with F(1) (first element in the vector) evaluating to the first equation and F(2) to the second. The function would accept a vector input, say x, which is = [ p ; v]. ie a vector of the two unknowns.
