A. TRANSLATION BETWEEN MATLABµ-TOOLS AND Xµ395
Note that the transpose and conjugate transpose operators are defineddifferently for
Matlab andXmath.
system/Dynamic System Functions
The following functions perform useful manipulations to, or information about, the state
of a system or Dynamic System.

varyi ng/pdm Functions
A large number of varyin g matrixoperations have been writtenin 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.
