ALEX Install Information


- Download the ALEX archive file in the directory where you
  want it to be. For example:
  	/usr/local/matlab/toolbox/

- Uncompress and tar the file

     gunzip Alex.beta1.tar.gz

     tar -xvfo Alex.beta1.tar

- Edit the alex.m file and make the few changes required.

- Setup the MATLAB path in order to access to ALEX from any
  directory. You can do this by adding the command:
        path(path, '/usr/local/matlab/toolbox/alex');
  to your startup.m file or typing it every time MATLAB is started.

- If the icol program does not run, try to recompile it.
  See the README.ALEX file in the icol.tar file.

Installation Completed.


To start ALEX just type alex at the MATLAB prompt:( >> alex )
Setting the following lines in the .Xdefaults file it will set up
an easy to read fontstyle for the MATLAB uimenu and uicontrols:
!MATLAB DEFAULT SETTING:
*fontList: -*-helvetica-medium-r-normal--14-*-*-*-*-*-*-*
!Figure window text font:
figure*fontList: -*-screen-*-*-*-*-16-*-*-*-*-*-*-*
!Figure window exponent text font
figure*expfontList: -*-helvetica-medium-r-normal--12-*-*-*-*-*-*-*

To use all the ALEX capabilities, both MATLAB 4.2c and the image
processing toolbox are required.
There is a new release of some of the Image processing toolbox (1.0)
functions at the Mathworks ftp site. Some bugs have been fixed and some have
been improved.


SGI
----
ALEX has been written and partially tested on an SGI computer. Thus no
particular changes to the code should be required.

Other Unix Machines
--------------
On other Unix machines it would be straightforward to run ALEX. The only
additional step is that the cmex files (all the .c files) should be recompiled
using the cmex compiler and the .mexsg files must be deleted.
The icol program must be recompiled too. See the README.ALEX file
in the icol.tar file.

PC and Mac
-----------
For PC or Mac version of MATLAB some changes should be made. The biggest
problem on a PC is that some of the files names are more than 8 characters.
Being able to run Matlab under windows 95 should avoid this problem.
We do not have PC or Mac version of MATLAB, so we cannot convert
ALEX to these platforms. ANYBODY INTERESTED IN THIS CONVERSION IS WELCOME.
