Hi Felipe, Thanks for your mail. There is actually some code I should have finished a long time ago in the "devel" folder [1]. There are commands "ctrbf" and "obsvf" which I'd like to modify such that they use the SLICOT library [2]. SLICOT is the foundation of the control package. The "acker" command is missing as well, but in the meantime you can try the more advanced "place" function. It offers better numerical reliability and can handle multiple-input-multiple-output systems. IMHO Octave's place is even better than Matlab's place because you can specify a boundary "alpha". Note that there is a PROJECTS file [3] where I list missing features. Of course, submissions are always welcome even if a missing feature is not on that list. And by using your own home-made functions you can impress your class even more and we give you credits ;-) You can send me your functions by e-mail and/or post them to the tracker that Juan proposed. Best regards, Lukas [1] http://octave.svn.sourceforge.net/viewvc/octave/trunk/octave-forge/main/control/devel/ [2] http://www.slicot.org/ [3] http://octave.svn.sourceforge.net/viewvc/octave/trunk/octave-forge/main/control/devel/PROJECTS?revision=8939&view=markup ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-novd2d _______________________________________________ Octave-dev mailing list Octave-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/octave-dev
