You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: cfmtri2.m
    path of file: ./repos/mesh2d/mesh-util
    
    the code of the file until where you have to start completion: function [vert,econ,tria] = cfmtri2(vert,econ)
%CFMTRI2 compute a conforming 2-simplex Delaunay triangulat-
%ion in the two-dimensional plane.
%   [VERT,CONN,TRIA]=CFMTRI2(VERT,CONN) computes the confor-
%   ming Delaunay trianguation, given the points VERT, and
%   edge constraints CONN. New points are inserted to bisect
%   edge constraints until all are recovered. VERT is a
%   V-by-2 array of XY coordinates to be triangulated, TRIA
%   is a T-by-3 array of vertex indexing, with each row
%   defining a triangle, such that VERT(TRIA(II,1),:),
%   VERT(TRIA(II,2),:) and VERT(TRIA(II,3),:) are the coord-
%   inates of the II-TH triangle. CONN is a C-by-2 array of
%   constraining edges, where each row def
