function A_safe = sanitize (A) %#ok
%SANITIZE sanitize a sparse adjacency matrix for graph partitioning.
% A_safe = sanitize(A) sanitizes an adjacency matrix by removing its diagonal
% and attempting to form a symmetric matrix (i.e. an undirected graph). If
% the input matrix is not symmetric, a symmetric matrix is formed using
% A_safe = (A + A')/2.
%
% Example:
% Prob = ssget('HB/west0479'); A = Prob.A;
% A_safe = sanitize(A);
% subplot(1,2,1); spy(A); subplot(1,2,2); spy(A_safe);
