RootLocs 3.7

ROOTLOCS 3.7 - a Root Locus plotting program

ROOTLOCS is an easy to use program for plotting Root Locus diagrams
of linear control systems. Given the positions in the complex plane of
the open loop poles and zeros of a system, ROOTLOCS plots the loci of
the system's closed loop poles as the gain of the system is increased
indefinitely starting from zero.

ROOTLOCS can handle systems with up to 20 poles and 20 zeros, and is
very fast. It offers a choice of working in either the S-Plane or the
Z-Plane and it can plot the loci of both positive and negative gain
systems. Several useful 'tools' are included for getting quantitative
information from the displayed root locus plots.

The current version of the program (3.7) incorporates several major
improvements over the previously archived version (3.5), including :
