A. TRANSLATION BETWEEN MATLAB µ-TOOLS AND Xµ 399
information.
A.4 System Interconnection
Simple interconnection has already been outlined in the augmentation section above.
The more complicated interconnection functions are almost identical in µ-Tools and Xµ.
The only real difference is the calling syntax of sysic.
Description µ-Tools function Xmath/Xµ equivalent
Redheffer (star) product starp starp
system interconnection sysic sysic
A.5 Model Reduction
The model reduction functions in Xµ are:
Description µ-Tools function Xmath/Xµ equivalent
residualization sresid sresidualize
state truncation strunc truncate
balanced realization sysbal balance
Hankel norm reduction hankmr ophank
The following frequency weighted model reduction functions have no equivalent in the
current version of Xµ. It is intended to introduce this functionality in the next version.
The functions are: sdecomp, sfrwtbal, sfrwtbld, sncfbal and srelbal.
