A. TRANSLATION BETWEEN MATLAB µ-TOOLS AND Xµ 395
Note that the transpose and conjugate transpose operators are defined differently for
Matlab and Xmath.
system/Dynamic System Functions
The following functions perform useful manipulations to, or information about, the state
of a system or Dynamic System.

varying/pdm Functions
A large number of varying matrix operations have been written in µ-Tools. These are
not required in the Xmath version as most of the functions operate on pdmsaswellas
matrices. The following table lists these functions for µ-Tools and Xmath. These are
only approximate functional equivalents — the more complicated functions differ in
some important respects.
