290 Chapter 6. Function Reference
The bounds, mubnds, are used to determine the ”worst-case” frequency for the
interpolation. The norm of pertsys is 1/(norm(Delta(jω))) where ωis the chosen
frequency. This is the smallest destabilizing perturbation at that frequency.
Both the interpolation frequency and the norm of pertsys can be specified via keywords.
The user may be interested only in certain frequency ranges and may have an assumed
norm bound on the perturbation (typically unity).
Components of pertsys (or all of it if appropriate)may be real valued gains rather than
dynamic systems.
Example
The use of mkpert is studied in context in the on-line help for musynfit and the manual
documentation for musynfit (page 299).
