function klu_install (metis_path)
%KLU_INSTALL compiles and installs the KLU, BTF, AMD, and COLAMD mexFunctions
%
% Example:
% klu_install
%
% KLU relies on AMD, COLAMD, and BTF for its ordering options, and can
% optionally use CHOLMOD, CCOLAMD, CAMD, and METIS as well. By default,
% CHOLMOD, CCOLAMD, CAMD, and METIS are compiled and used by KLU.
%
% You must type the klu_install command while in the KLU/MATLAB directory.
