Calculating the density of the estimated regular vine at the point(s) val.
cal.vine(obj,val,cores)Vine object of class 'pencopula'.
Values in which the current R-vine should be evaluated.
Default=NULL, the number of cpu cores used for parallel computing can be specified.
The returing values are the density of the current R-vine at the point(s) 'val'.
The current R-vine is evaluated in val and the corresponding density values are returned.
