SLICOT Library Root Directory
-----------------------------

SLICOT - Subroutine Library In COntrol Theory - is a general purpose basic
mathematical library for control theoretical computations.  The library
provides tools to perform essential system analysis and synthesis tasks.
The main emphasis in SLICOT is on numerical reliability of implemented
algorithms and the numerical robustness and efficiency of routines.
Providing algorithmic flexibility and the use of rigorous implementation
and documentation standards are other SLICOT features.

The SLICOT Library is available as standard Fortran 77 code in double
precision.  Each user-callable subroutine for control computations is
accompanied by an example program which illustrates the use of the
subroutine and can act as a template for the user's own routines.

The SLICOT Library is organized by chapters, sections and subsections.
The following chapters are currently included:

A : Analysis Routines
B : Benchmark and Test Problems
D : Data Analysis
F : Filtering
I : Identification
M : Mathematical Routines
N : Nonlinear Systems
    (not yet available, except for some auxiliary routines for Wiener systems)
S : Synthesis Routines
T : Transformation Routines
U : Utility Routines

SLICOT Library Root Directory contains few, basic files for the SLICOT Library
distribution and generation.  When distributed, SLICOT software comes with
several filled-in subdirectories (benchmark_data, doc, examples, examples77,
src, and src_aux), and five files in this root
directory:
- this file, readme,
- the file Installation.txt, describing the SLICOT software installation,
- the main SLICOT Library documentation index, libindex.html, and
- two template files for building the object library and executable programs,
  make.inc and makefile,
- GNU GENERAL PUBLIC LICENSE Version 2 text file.
The last two files might need few changes for being adapted to the specific
platform used.  Details about installing/updating the SLICOT software are
given in the file Installation.txt.

After software installation, this directory will also contain the library
file slicot.a or slicot.lib, for Unix or Windows platforms, respectively.
The library file could then be linked in applications programs, as usual.
Specific examples are contained in the directories examples and examples77.
The on-line documentation of the SLICOT user's callable routines is
accessible via the main SLICOT Library documentation index, libindex.html.
This file also contains a link to the documentation of the lower-level,
support routines.

The SLICOT Library is built on LAPACK (Linear Algebra PACKage) and BLAS
(Basic Linear Algebra Subprograms) collections.  Therefore, these
packages should be available on the platform used.
