+++ Introduction +++

Zkcm library is a C++ library for multi-precision complex-number matrix calculations. It provides several functionalities including singular value decomposition, tensor product calculation, and tracing-out operations.

It is based on the GNU MP (GMP) and MPFR libraries, which are usually found as standard packages in recent Linux distributions.

Documentations are found in the "doc" directory of the package. They are also placed at [Documents] in the PDF file format.

+++ Requirements +++

MPFR >= 3.0.0 and GMP. In addition, a UNIX(-like) environment with GNU tools is required, such as some Linux distribution, some BSD system, Cygwin on Windows, etc., to compile the zkcm library.

+++ Installation +++

See the document in the directory ./doc. In short, it is just a standard process:

$ ./configure
$ make
# make install


In case you have errors when running configure, maybe you may type

$ autoconf
$ autoheader
$ ./configure
$ make
# make install


Or, you may use a copy of Makefile.orig found in the tar ball for Makefile.

+++ Making your program with zkcm library +++

See the [Documents] for details. In short, your source file should write

#include "zkcm.hpp"


and use classes and appropriate functions defined in the header files of the zkcm library.

+++ Compilation of your program +++

The zkcm library is based on the GMP and MPFR libraries. Thus, you probably need flags

   -lm -lmpfr -lgmp -lgmpxx


in addition to

   -lzkcm


to compile your program with the zkcm library using g++.

Note: As the zkcm library is a static library, your program should be recompiled when a new version of zkcm is installed.

+++ Uninstalling the zkcm library +++

You may uninstall the library by

# make uninstall

This will remove not only the library files but also the directory ${prefix}/share/doc/zkcm-x.x.x completely. Thus, make sure that you don't have your own files in the directory before typing the above command.
