1 function h=GetMaxLengthEdges(q,me)
2 % function h=GetMaxLengthEdges(q,me)
3 % Computation of the maximal value of edge lengths
4 %
5 % Parameters:
6 % q: Array of vertices coordinates, `2\times\nq` array. <br/>
7 % `{\q}(\il,j)` is the
8 % `\il`-th coordinate of the `j`-th vertex, `\il\in\{1,2\}` and
9 % `j\in\ENS{1}{\nq}`
10 % me: Connectivity array, `3\times\nme` array ('int32'). <br/>
11 % `\me(\jl,k)` is the storage index of the
12 % `\jl`-th vertex of the `k`-th triangle in the array `\q` of vertices coordinates, `\jl\in\{1,2,3\}` and
13 % `k\in{\ENS{1}{\nme}}`.

15 % Return values:
16 % h: maximal length of an edge in the mesh
