README for Alex Petrov's Matlab UTILS ver 1.1.1, released 2008-02-22.

This archive contains MATLAB software supporting the day-to-day work
of a cognitive modeler with an interest in psychophysics and statistics.
The particular subfolders, or "toolboxes" included in this release are:

* ANOVA Toolbox                         Ver 1.0    20-Dec-2002
* ACT-R Base-Level Activation Toolbox   Ver 2.0    12-Feb-2006
* General Utilities Toolbox             Ver 1.3    06-Jun-2006
* Image-Processing Utilities Toolbox    Ver 1.4    06-Dec-2007
* Nominal Statistics Toolbox            Ver 1.2    21-Oct-2005
* Parameter Search Toolbox              Ver 1.2    16-Aug-2007
* PolarGraph Utilities Toolbox          Ver 1.0    02-Dec-2004
* Regression Utilities Toolbox          Ver 1.0    21-Oct-2005
* Subject-Database Toolbox              Ver 1.1    11-Mar-2005

Most of these contain a few one-line functions, but they can
enhance one's productivity considerably.  There are also some
non-trivial algorithms, such as locally weighted regression.
Each toolbox has its own Contents file -- go there for details.

All functions are simple .m files that should work on any version
of Matlab under any operating system. Some utilities depend on the
Matlab's Statistics, Image, and Optimization Toolboxes. The MovieStruct
functions in the image-processing toolbox above are designed to work
with the RUSH utility in PsychToolbox (http://psychtoolbox.org/).

To install, simply unzip the archive in a directory of your choice
and execute the INSTALL_UTILS script to add the subdirectories to
Matlab's path.
