This form is commonly used in control = theory. It may be of great use both for simulation and calculation of = control parameters.

In the thesis "Automatic generation of optimal concurrent = error detection circuits for linear timeinvariant analog electronic = systems" marked Eindhoven University Of Technology author Peters, A.W. = mention he wrote some software in Octave for this purpose.
