    00001 function lbe=EdgeLengthOpt(be,q)
    00002 % function lbe=EdgeLength(be,q)
    00003 %   Computation of the lengths of edges in the mesh
    00004 %   - Optimized version
    00005 %
    00006 % Parameters:
    00007 %  be: Connectivity array for boundary edges, `2\times\nbe` array.<br/>
    00008 % `\be(\il,l)` is the storage index of the
    00009 %  `\il`-th  vertex of the `l`-th edge in the array `\q` of vertices coordinates, `\il\in\{1,2\}` and
    00010 %       `l\in{\ENS{1}{\nbe}}`.
    00011 %  q: Array of vertices coordinates, `2\times\nq` array. <br/>
    00012 %  `{\q}(\il,j)` is the
    00013 %  `\il`-th coordinate of the `j`-th vertex, `\il\in\{1,2\}` and
    00014 %  `j\in\ENS{1}{\nq}`
    00015 %
    00016 %
    00017 % Return values:
    00018 %  lbe: Array of edges lengths,  `1\times\nbe` array. `lbe(j)`  is the length of the `j`-th edge.
