A. TRANSLATION BETWEEN MATLABµ-TOOLS AND Xµ397
Miscellaneous Utilities
Several utilities are provided in µ-Tools. These are subroutines used by other µ-Tools
functions which mayb e of more general use.

A.2 Matrix Information, Display and Plotting
Xmath provides matrix/data object size information via a variable window. There is no
Matlab equivalentfor this functionality. Command window info rmation can be
obtained via the following functions.
Description µ-Tools function Xmath/Xµequivalent
matrix information minfo check,size,is
list workspace whos who
Plotting of varyin g matricesis provided by the Matlab µ-Tools function vplot.As
pdms are a native dataob ject in Xmath,the standard Xmath plot function will
correctly plot a pdm. Multiple calls will overlay the data, even if the domains differ. The
Xµfunction ctrlplot is provided for more control specific plots: Bode, Nyquist,
Nichols, log magnitude, etc..
Both Matlab and Xmath allowinteractive manipulation of the graphical data and
storage and retrievalof plots from the workspace or the underlying file system.
