Introduction to the Companion MATLAB Codes 

For use with the book "Feedback systems analysis and design with 
MATLAB", by Professor Dingyu Xue, Tsinghua University Press 2000
(Chinese version)

A group of MATLAB functions was designed to illustrate the use
of system analysis and design tasks presented in the book.  There
is unfortunately no comments in the companion software itself,
and there are adequate illustrations on the software in the book.

MATLAB 5.x is required to run those files.  Some of the files may
required the Control Systems Toolbox, Robust Control Toolbox and
Simulink, which are all products of the MathWorks.

For further details about the software, or for codes for MATLAB 4.x,
please write to the author:
