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: SuiteSparse_install.m
    path of file: ./repos/SuiteSparse
    
    the code of the file until where you have to start completion: function SuiteSparse_install (do_demo)
%SuiteSparse_install: compiles and installs all of SuiteSparse
% A Suite of Sparse matrix packages, authored or co-authored by Tim Davis.
%
% Packages in SuiteSparse:
%
% GraphBLAS      graph algorithms via sparse linear algebra (graphblas.org)
% Mongoose       graph partitioner
% SPEX           solve sparse Ax=b exactly
% UMFPACK        sparse LU factorization (multifrontal)
% CHOLMOD        sparse Cholesky factorization, and many other operations
% AMD            sparse symmetric approximate minimum degree ordering
% COLAMD         sparse column approximate minimum degree ordering
% CAMD           constrained AMD
% CCOLAMD        constrained COLAMD
% CSparse        a Concise Sparse matrix package (32-bit or 64-bit, real only)
% CXSparse       extended version of CSparse (32-bit/64-bit/real/complex)
% ssget          interface to SuiteSparse Matrix Collection
% KLU            sparse LU factorization (left-looking)
% BTF            permutation to block triangular form (like dmperm)
% LDL            sparse LDL' factorization
% SuiteSparseCollection   tools for managing the SuiteSparse Matrix Collection
% RBio           read/write Rutherford/Boeing files
% SSMULT         sparse matrix times sparse matrix
% MESHND         2D and 3D regular mesh generation and nested dissection
% FACTORIZE      an object-oriented solver for x=A\b
% SPARSEINV      sparse inverse subset; computes entries of inv(sparse(A))
% MATLAB_Tools   various simple m-files and demos
% SuiteSparseQR  sparse QR factorization
% spqr_rank      MATLAB toolbox for sparse rank deficient matrices
%
% Example:
%    SuiteSparse_install        % compile and prompt to run each package's demo
%    SuiteSparse_install(0)     % compile but do not run the demo
%    SuiteSparse_install(1)     % compile and run the demos with no prompts
%    help SuiteSparse           % for more details
%
% See also AMD, COLAMD, CAMD, CCOLAMD, CHOLMOD, UMFPACK, CSPARSE, CXSPARSE,
%      ssget, RBio, SuiteSparseCollection, KLU, BTF, MESHND, SSMULT, LINFACTOR,
%      SPOK, SPQR_RANK, SuiteSparse, SPQR, PATHTOOL, PATH, FACTORIZE,
%      SPARSEINV, Mongoose, GraphBLAS, SPEX.
%
% This script installs the full-featured CXSparse rather than CSparse.
%
% If you get errors building or using METIS, just remove the
% CHOLMOD/SuiteSparse_metis folder.  This often occurs on Windows.
%
% Before using SuiteSparse_install, you must compile the GraphBLAS library for
% use in MATLAB.  In the system shell while in the SuiteSparse folder, type
% "make gbmatlab".  You must then either install the libgraphblas_matlab.so
% library system-wide ( cd GraphBLAS/GraphBLAS ; make ; sudo make install), or
% install your own copy ( make local ; make install ) and then add the
% SuiteSparse/lib folder to your LD_LIBRARY_PATH.  Restart MATLAB after
% compiling libgraphblas_matlab.so.
