Contents.m a list of contents for 'help SuiteSparse' in MATLAB.
CSparse a concise sparse matrix package, developed for my
book, "Direct Methods for Sparse Linear Systems",
published by SIAM. Intended primarily for teaching.
It does have a 'make install' but I recommend using
CXSparse instead. In particular, both CSparse and CXSparse
have the same include filename: cs.h.
This package is used for the built-in DMPERM in MATLAB.

CXSparse_newfiles
author: David Bateman, Motorola
CXSparse CSparse Extended. Includes support for complex matrices
and both int or long integers. Use this instead of CSparse
for production use; it creates a libcsparse.so (or *dylib on
the Mac) with the same name as CSparse. It is a superset
of CSparse. Any code that links against CSparse should
also be able to link against CXSparse instead.

Some codes optionally use METIS 5.1.0. This package is located in SuiteSparse in the metis-5.1.0 directory. Its use is optional, so you can remove it before compiling SuiteSparse, if you desire. The use of METIS will improve the ordering quality. METIS has been slightly modified for use in SuiteSparse; see the metis-5.1.0/README.txt file for details. SuiteSparse can use the unmodified METIS 5.1.0, however. To use your own copy of METIS, or a pre-installed copy of METIS use 'make MY_METIS_LIB=-lmymetis' or 'make MY_METIS_LIB=/my/stuff/metis-5.1.0/whereeveritis/libmetis.so MY_METIS_INC=/my/stuff/metis-5.1.0/include'. If you want to use METIS in MATLAB, however, you MUST use the version provided here, in SuiteSparse/metis-5.1.0. The MATLAB interface to METIS required some small changes in METIS itself to get it to work. The original METIS 5.1.0 will segfault MATLAB.

```

METIS 5.0.1 is distributed with SuiteSparse, and is Copyright (c) by George Karypis. Please refer to that package for its License.

Uncompress the SuiteSparse.zip or SuiteSparse.tar.gz archive file (they contain the same thing). Suppose you place SuiteSparse in the /home/me/SuiteSparse folder.

Add the SuiteSparse/lib folder to your run-time library path. On Linux, add this to your ~/.bashrc script, assuming /home/me/SuiteSparse is the location of your copy of SuiteSparse:

```
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/SuiteSparse/lib
export LD_LIBRARY_PATH
```

For the Mac, use this instead, in your ~/.zshrc script, assuming you place SuiteSparse in /Users/me/SuiteSparse:

```
DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Users/me/SuiteSparse/lib
export DYLD_LIBRARY_PATH
```

Next, compile the GraphBLAS library. In the system shell while in the SuiteSparse folder, type "make gbinstall" if you have MATLAB R2020b or earlier, or type "make gbrenamed" if you have MATLAB 9.10 (R2021a) or later.

Then in the MATLAB Command Window, cd to the SuiteSparse directory and type SuiteSparse_install. All packages will be compiled, and several demos will be run. To run a (long!) exhaustive test, do SuiteSparse_test.

Save your MATLAB path for future sessions with the MATLAB pathtool or savepath commands. If those methods fail because you don't have system-wide permission, add the new paths to your startup.m file, normally in Documents/MATLAB/startup.m. You can also use the SuiteSparse_paths method to set all your paths at the start of each MATLAB session.

For Windows: My apologies, but I don't support Windows so you will need to revise the above instructions for Windows yourself.

Type the following in this directory:

```
make ; make install
```

or, if want to use GraphBLAS in recent versions of MATLAB, do:

```
make ; make gbrenamed ; make install
```

All libraries will be created and copied into SuiteSparse/lib. All include files need by the applications that use SuiteSparse are copied into SuiteSparse/include. All user documenation is copied into SuiteSparse/share/doc.

Be sure to first install all required libraries: BLAS and LAPACK for UMFPACK, CHOLMOD, and SPQR, and GMP and MPFR for SLIP_LU. Be sure to use the latest libraries; SLIP_LU requires MPFR 4.0 for example.

When compiling the libraries, do NOT use the INSTALL=... options for installing. Just do:

```
make
```

or to compile just the libraries without running the demos, do:

```
make library
```

Any program that uses SuiteSparse can thus use a simpler rule as compared to earlier versions of SuiteSparse. If you add /home/me/SuiteSparse/lib to your library search patch, you can do the following (for example):

```
S = /home/me/SuiteSparse
cc myprogram.c -I$(S)/include -lumfpack -lamd -lcholmod -lsuitesparseconfig -lm
```

To change the C and C++ compilers, and to compile in parallel use:

```
AUTOCC=no CC=gcc CX=g++ JOBS=32 make
```

for example, which changes the compiler to gcc and g++, and runs make with 'make -j32', in parallel with 32 jobs.

Now you can install the libraries, if you wish, in a location other than SuiteSparse/lib, SuiteSparse/include, and SuiteSparse/share/doc, using 'make install INSTALL=...'

Do 'make install' if you want to install the libraries and include files in SuiteSparse/lib and SuiteSparse/include, and the documentation in SuiteSparse/doc/suitesparse-VERSION. This will work on Linux/Unix and the Mac. It should automatically detect if you have the Intel compilers or not, and whether or not you have CUDA. If this fails, see the SuiteSparse_config/SuiteSparse_config.mk file. There are many options that you can either list on the 'make' command line, or you can just edit that file. For example, to compile with your own BLAS:

```
make BLAS=-lmyblaslibraryhere
```

NOTE: Use of the Intel MKL BLAS is strongly recommended. The OpenBLAS can result in severe performance degradation, in CHOLMOD in particular.

To list all configuration options (but not compile anything), do:

```
make config
```

Any parameter you see in the output of 'make config' with an equal sign can be modified at the 'make' command line.

If you do "make install" by itself, then the packages are all installed in SuiteSparse/lib (libraries), SuiteSparse/include (include .h files), and SuiteSparse/doc/suitesparse-VERSION (documentation). To install in /usr/local, the default location for Linux, do:

```
make library
sudo make install INSTALL=/usr/local
```

If you want to install elsewhere, say in /my/path, first ensure that /my/path is in your LD_LIBRARY_PATH. How to do that depends on your system, but in the bash shell, add this to your ~/.bashrc file:

```
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/my/path
export LD_LIBRARY_PATH
```

You may also need to add SuiteSparse/lib to your path. If your copy of SuiteSparse is in /home/me/SuiteSparse, for example, then add this to your ~/.bashrc file:

```
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/SuiteSparse/lib:/my/path
export LD_LIBRARY_PATH
```

For the Mac, use this instead:

```
DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/home/me/SuiteSparse/lib:/my/path
export DYLD_LIBRARY_PATH
```

Then do the following (use "sudo make ..." if needed):

```
make library
make install INSTALL=/my/path
```

which puts the files in /my/path/lib, /my/path/include, and /my/path/doc. If you want to selectively put the libraries, include files, and doc files in different locations, do:

```
make install INSTALL_LIB=/my/libs INSTALL_INCLUDE=/myotherstuff/include INSTALL_DOC=/mydocs
```

for example. Any term not defined will be set to its default, so if you don't want to install the documentation, but wish to install the libraries and includes in /usr/local/lib and /usr/local/include, do:

```
make install INSTALL_DOC=/tmp/doc
```

which copies the documentation to /tmp/doc where you can then remove it later.

Both the static (.a) and shared (.so) libraries are compiled. The lib.a libraries are left in the package Lib folder (AMD/Lib/libamd.a for example). The main exception to this rule is the SuiteSparse_config library, which is in SuiteSparse/libsuiteSparseconfig.a. SuiteSparse_config is required by all packages. The (extremely) optional xerbla library is also an exception, but it is highly unlikely that you need that library.

The 'make uninstall' takes the same command-line arguments.

(1) Use the right BLAS and LAPACK libraries. Determine where your BLAS and LAPACK libraries are. If the default 'make' does not find them, use 'make BLAS=-lmyblaslibraryhere LAPACK=-lmylapackgoeshere'

(2) Install Intel's Threading Building Blocks (TBB). This is optionally used by SuiteSparseQR. Refer to the User Guide in SuiteSparse/SPQR/Doc/spqr_user_guide.pdf for details.

(3) Determine what other command line options you need for 'make'. All options can be set at the 'make' command line without the need to edit this file. Browse that file to see what options you can control. If you choose different options and wish to recompile, be sure to do 'make distclean' in this directory first, to remove all files not in the original distribution.

(4) Type "make" in this directory. All packages will be be compiled. METIS
5.1.0 will be compiled if you have it (note that METIS require CMake to
build it). Several demos will be run. To compile just the libraries,
without running any demos, use "make library". The libraries will appear
in */Lib/*.so.* (*.dylib for the Mac). Include files, as needed by user
programs that use CHOLMOD, AMD, CAMD, COLAMD, CCOLAMD, BTF, KLU, UMFPACK,
LDL, etc. are in */Include/*.h. The include files required by user
programs are then copied into SuiteSparse/include, and the compiled
libraries are copied into SuiteSparse/lib. Documentation is copied into
SuiteSparse/doc. The GraphBLAS libraries are created by cmake and placed
in GraphBLAS/build. NOTE: on Linux, you may see some errors when you
compile METIS ('make: *** No rule to make target 'w'.). You can safely
ignore those errors.

(6) To install, type "make install". This will place copies of all libraries in SuiteSparse/lib, and all include files in SuiteSparse/include, and all documentation in SuiteSparse/doc/suitesparse-VERSION. You can change the install location by "make install INSTALL=/my/path" which puts the libraries in /my/path/lib, the include files in /my/path/include, and documentation in /my/path/doc. These directories are created if they do not already exist.

(7) To uninstall, type "make uninstall", which reverses "make install" by removing the SuiteSparse libraries, include files, and documentation from the place they were installed. If you pass INSTALL_***= options to 'make install', you must pass the same to 'make uninstall'.

See scikit-sparse and scikit-umfpack for the Python interface via SciPy:
