plotting capabilities. With the support of the small IS group at the Lockheed
Skunk Works, I wrote dynamic JCL code and assembly language interfaces to
accomplish this task.
When MATLAB became commercially available on IBM PCs and Apple
Macintosh computers, these computers were brought into Lockheed along with
this software. With the aid of Hank Donald, then an engineer at Lockheed and
now at Ford (where he has continued to wor k on MATLAB, Simulink, and State-
flow standards), we brought UNIX workstations and the next generation of
MATLAB and Matrix-X based tools into the Skunk Works. These workstations
were also used to introduce us to early graphical modeling tools including
Grumman’s Protoblock, ISI’s SystemBuild, X-ANALOG’s NL-SIM, and
ADI’s BEACON.
The introduction of MATLAB and additional software tools by The
MathWorks led to the need for additional training modules and instructors.
Hank Donald helped generate the initial training materials for MEX-files. His
desire for a manual Simulink switch and other featur es within Simulink really
motivated The MathWorks’ developers to improve the early versions of Simulink
and make it the excellent tool you have today. He also participated in many of the
early training courses within Lockheed. Shah Torgenson wrote some of the
earliest training materials on cells and structures and helped tremendously
with several of the training classes we offered at Lockheed. Bob Radford and
Bill Wood were also very helpful in their support and participation in several
MATLAB training classes at Lockheed. The human resources department at
Lockheed and later Lockheed Martin helped support some of this work. Jim
Buffington and his engineers, including Mike Niestroy in Fort Worth,
along with the F-22 program, including Dave Seto, also provided great help in
expanding this training throughout Lockhee d Martin.
I appreciated The MathWorks providing a copy of Simulab for early evalu-
ation work. This software then developed into the Simulink modeling package.
Similarly, The MathWorks provided me with the first version of Stateflow
software, which was then not integrated into Simulink. All following versions
of Stateflow software were integrated within the Stateflow environment.
Many others have provided me with assistance at The MathWorks. Again,
I apologize for those that I have missed. Russell Scarlata, who had the Lockheed
account at The MathWorks, provided me with years of excellent help and
support. John Binder also provided several years of excellent suppor t and encour-
aged me to develop this book. Dick Gram, previously at Grumman and then at
The MathWorks, provided many great flight controls modeling ideas. Courtney
Esposito, of the MATLAB Book Program, has provided great software and
publishing support for my previous book, Applications of Robust Control to
Nonlinear Systems, as well as this book.
I would like to thank the University of Kansas Aerospace Engineering Short
Course Program for aiding me in offering MATLAB and Simulink as both an
on-site class and as a course offered to the general public. Finally, I would like
to thank the staff of the Department of Aerospace Engineering at the University
of Kansas for their support in my writing and completing this book.
