How can I define the input for this function?

In the below function it is explained how to set the input:

function nMM=grMaxMatch(E)
% Function nMM=grMaxMath(E) solve the maximal matching problem.
% Input parameter: 
%   E(m,2) or (m,3) - the edges of graph and their weight;
%     1st and 2nd elements of each row is numbers of vertexes;
%     3rd elements of each row is weight of edge;
%     m - number of edges.
%     If we set the array E(m,2), then all weights is 1.

However, I can not understand how to define E. For example, for a graph with edges like [(1,2),(2,3)] how should I set up E?

For [(v1,v2),(v3,v4)]:

E(1,1) = v1;
E(1,2) = v2;
E(2,1) = v3;
E(2,2) = v4;

Complete function is here

So for my example

E=[1 2;
   2 3];

But this does not work with as an input for that function!

Then you should contact the author of the code. He/She knows best how to cope with possible problems.
