This package provides input/output blocks where every
block is available in a **continuous** and a **discrete** (sampled)
representation. A block is defined via its **continuous
parameterization**. By specifying a discretization method and
a sample time, the discrete representation is automatically
derived from the continuous form. The defaults of the most
important options for **all blocks** are set in the global SampleClock
component (via inner/outer).
As a result, it is, e.g., easy to switch quickly
between a continuous and a discrete representation of all
blocks of a controller.

Examples to demonstrate the technique are given in the package Examples. Especially, the continuous or discrete control of a simple flexible drive with a P-PI cascade controller is demonstrated in example SimpleControlledDrive.
