RMCT for Scilab: functions

TOOLBOXES TUTORIAL

Links to help files

These help files are expected to give an idea of the potentialities of the toolbox. Some of them contain an illustrative example but more detailed examples are available on the tutorial page. Eigenstructure assignment options (desired eigenvector, projection and so on) are explained here.
