So, drawing from:
Linear Control Systems Analysis and Design
Conventional and Modern
Third Edition
John D'Azzo and Constantine Houpis
1988
So, above I talked about the matrix program TOTAL, coming from a thesis by S. J. Larimer, at the Air Force Institute of Technology, Wright-Patterson AFB Ohio, 1978
Now we also have other Air Force Institute of Technology theses listed:
Colgate, A. "INTERAC -An Interactive Software Package for Direct Digital Control Design 1977
Gembrowski, C. J. "Continued Development of an Interactive Computer-Aided Design (CAD) Package for Discrete and Continuous Control System Analysis and Synthesis, 1982
Hernandez, G. "An Interactive Computational Aerodynamics Analysis Program, 1980
Kennedy, A. "The Design of Digital Controllers for the C-141 Aircraft Using Entire Eigenstructure Assignment and the Development of an Inter-Active Computure Design Program, 1979
Logan, G. T. "Development of an Interactive Computer-Aided Design Program for Digital and Continuous Control System Analysis and Synthesis", 1982
O'Brien, L. "A Consolidated Computer Program for Control System Design", 1976
And I am sure that MatLAB arose from this work.
