Computing the v-function of a pair-copula
The function computes the h-function, i.e., it evaluates the conditional distribution function of U2|U1 at u2, given U1=u1. Possible copula families:

U = PairCopulaVfun(family,u1,u2,theta) Rotated pair-copulas U = PairCopulaVfun(family,u1,u2,theta,rotation)
family = The copula family. u1 = A (n x 1) dimensional vector of values lying in [0,1]. u2 = A (n x 1) dimensional vector of values lying in [0,1]. theta = The parameter vector for the pair-copula. rotation = The degree of rotation, i.e., either 90, 180 or 270. No rotation is achieved by letting the rotation argument empty or by choosing 0 rotation.
U = n dimensional vector of probabilities (sometimes called pseudo-observations), which are lying strictly in [0,1].
