cosnov_1d

 COSNOV_1D : Constructs the 1D (local mesh ---> global mesh) map
 
 [nov]=cosnov_1d(npdx,ne,nov) computes the 2-indeces array nov:
       nov(i,ie) = is the index, with respect to global numbering,
                   associated to node i of element ie.

 Input: npdx = number of nodes in one element (the same in every element)
        ne   = number of elements
        nov  = zeros(max(npdx),ne)
 Output: nov = 2-indeces array of local to global map.
