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: find_outermost_boundary.m
    path of file: ./repos/spm12/external/fieldtrip/private
    
    the code of the file until where you have to start completion: function [outermost, inside] = find_outermost_boundary(bnd)

% FIND_OUTERMOST_BOUNDARY locates outermost compartment of a BEM model
% by looking at the containment of the triangular meshes describing 
% the surface boundaries
%
% [outermost] = find_innermost_boundary(bnd)
%
% with the boundaries described by a struct-array bnd with
%   bnd(i).pnt  vertices of boundary i (matrix of size Nx3)
%   bnd(i).tri  triangles of boundary i (matrix of size Mx3)
