( Last update: January 09, 2013)
This page provides the MatLab codes (.m files) of LMI
conditions published in recent papers of my authoring (or
co-authoring). The routines run under the MatLab environment and
require
YALMIP
as the LMI parser and
SeDuMi
as the LMI solver. If you use the programs in your research, paper or
thesis, please acknowledge this page.
Important: This page has not been updated since long time. The reason is that any parameter-dependent LMI with parameters lying in the unit simplex or in a hyperrectangle can be systematically treated in a high level programming language, implemented in the Matlab (or Octave) toolbox Robust LMI Parser - ROLMIP. Please, visit the
ROLMIP website for more information. See also the
paper.
