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: safe_edgecut.m
    path of file: ./repos/SuiteSparse/Mongoose/MATLAB
    
    the code of the file until where you have to start completion: function partition = safe_edgecut(G,O,A)
%SAFE_EDGECUT sanitizes and computes an edge cut of a graph.

    
function partition = safe_edgecut(G,O,A)
%SAFE_EDGECUT sanitizes and computes an edge cut of a graph.
%   safe_edgecut sanitizes the graph adjacency matrix by removing its diagonal
%   and attempting to form a symmetric matrix from the input. After
%   sanitization, an edge cut of the graph is computed and returned as a binary
%   array.
%
%   partition = SAFE_EDGECUT(G) assumes default options and no vertex weights
%   (i.e. all vertex weights are 1). The partition is returned as a binary
%   array.
%
%   partition = SAFE_EDGECUT(G, O) uses the options struct to define how the
%   edge cut algorithms are run.
%
%   partition = SAFE_EDGECUT(G, O, A) initializes the graph with vertex weights
%   provided in the array A such that A(i) is the vertex weight of vertex i.
%
%   Example:
%       Prob = ssget('HB/494_bus'); A = Prob.A;
%       part = safe_edgecut(A);
%       perm = [find(part) find(1-part)];
%       A_perm = A(perm, perm); % Permute the matrix
%       spy(A_perm);
