Showcase of some new features

In the demos to follow, we shall make use of fairly standard notations:

G denotes the physical plant under consideration.
P is used for the augmented plant describing the $H_\infty$ problem. The latter includes weighting functions, disturbances and regulated signals reflecting design requirements.
The symbols nu and ny stand for the dimensions of the control u & measurement signals y, respectively.
The symbols nw and nz are the dimensions of the disturbance w and objective or regulated signals z.
The symbol r refers to reference signals or set-point inputs.

In complex problems, we recommend using CONNECT to generate synthesis interconnections P or SIMULINK in conjunction with LINLFT for diagramatic derivations.
