  For an easy use of model order reduction techniques in applications, software
solutions are needed. In this paper, we describe the MORLAB, Model Order
Reduction LABoratory, toolbox as an efficient implementation of model reduction
techniques for dense, medium-scale linear time-invariant systems. Giving an
introduction to the underlying programming principles of the toolbox, we show
the basic idea of spectral splitting and present an overview about implemented
model reduction techniques. Two numerical examples are used to illustrate
different use cases of the MORLAB toolbox.
