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: isfeat2.m
    path of file: ./repos/mesh2d/mesh-util
    
    the code of the file until where you have to start completion: function [is,bv] = isfeat2(pp,ee,tt)
%ISFEAT2 return "feature" status for the triangles in a two-
%dimensional constrained triangulation.
%   [STAT] = ISFEAT2(VERT,EDGE,TRIA) returns STAT(II) = TRUE
%   for any triangle including a sufficiently "sharp" angle
%   located at the apex of any two constrained edges. Sharp
%   features have angles of greater-than ACOS(+0.8) degrees.
