A free MATLAB clone exists under the name OCTAVE How to install OCTAVE for Windows and some info in the following: New2022 version 7.3.0: Octave There is now a free MATLAB clone with IDE for Windows, (i.e. with a Graphical User interface with Command Window, Editor, Workspace and Command History etc as in the MATLAB GUI.) If You want to try it out check out: http://wiki.octave.org/Octave_for_Microsoft_Windows NB: Simply install one of the newest exeversions. Se the following Windows “print screan” picture file for illustrating the Octave IDE (or GUI) In my opinion, the latest Octave Matlab clone is the simplest to use, alternative to Matlab (for the Matlab users) as well as new users. The plotting facilities is in my opinion for the moment to poor in Octave, but the software is free. I have even tried out the DSR Toolbox for MATLAB under Octave, and it works (exept for a minor plotting bug). There are also Optimization functions for QP problems (the qpm function) and Nonlinear Programming function. Se all packages under the Documentation toolbar (lower left button in the IDE (picture enclosed)). How to install the Control System Toolbox and other packages In the OCTAVE command window go to the srcfolder where You have installed OCTAVE. >> cd c:\octave\octave3.8.2\src This will install the control toolbox from the net, because the forge flag is used. Actually, all packages comes with the OCTAVE installation. Info about all packages, optim, image etc. is obtained from the helpmenu + Octave Packages.. An alternative to the above is to first prepare all packages for installation and then instal the actual package. From the src folder do the following: >> cd c:\octave\octave3.8.2\src Teacher: David Di Ruscio
