For installation:

1. Unpack the file

   -- on a UNIX system, use "gunzip" and "tar" : 

      % gunzip iqcbXYZ.tar.gz
      % tar -xvf iqcbXYZ.tar
 
   -- on Win95, Win98, or WinNT, une, for example, "WinZip"

   The unpacking should produce a directory "iqc_beta" with several 
   sub-directories. The directory structure is:

       iqc_beta --+-- absttools -- @abst
                  |                                +-- v52 
                  +-- application -+- hysteresis --+ 
                  |                |               +-- v53 
                  |                +- ofs
                  |                |
                  |                +- rfs
                  |                |
                  |                +- sat
                  |
                  +-- cpm -- subfunctions
                  |         
                  +-- iqctools  -- iqclib
                  |
                  +-- lmitools
                  |
                  +-- tests

2. Include those subdirectories into the MATLAB search path. This can 
   be done by putting instructions 

   path(path,'path_to_iqc_beta/absttools')
   path(path,'path_to_iqc_beta/iqctools')
   path(path,'path_to_iqc_beta/iqctools/iqclib')
   path(path,'path_to_iqc_beta/lmitools')
   path(path,'path_to_iqc_beta/cpm')
   path(path,'path_to_iqc_beta/cpm/subfunctions')
   path(path,'path_to_iqc_beta/application')
   path(path,'path_to_iqc_beta/application/hysteresis/v52')
   path(path,'path_to_iqc_beta/application/hysteresis/v53') 
   path(path,'path_to_iqc_beta/application/ofs')
   path(path,'path_to_iqc_beta/application/rfs') 
   path(path,'path_to_iqc_beta/application/sat')
   path(path,'path_to_iqc_beta/tests')

   into your "startup.m" file, where "path_to_iqc_beta" is the path to 
   the directory "iqc_beta".

3. We suggest users put their own application files, if there is any, in 
   a new subdirectory under the directory 'application'. Remember to include 
   that subdirectory in to the MATLAB search path. 

4. You can test the installation by typing 

   >> iqc_beta_test

   to the MATLAB prompt. If everything is as expected, the last line
   of this program's output will be

   ***********TESTING OK!!!

5. Please report any problems or bugs to Alexandre Megretski at 
   ameg@mit.edu or Chung-Yao (Isaac) Kao at cykao@mit.edu. We will try
   to fix them as quickly as possible.
