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.
