Time delays and sample-and-hold operations in hybrid computation can cause serious stability problems, with the difficulty that considerable time and effort is wasted if this instability is not known in advance of programming the hybrid computer. A method of analysis exists which can be used to predict the stability of a given computing scheme. Although many problems can be solved by direct analysis, large-sized problems present some difficulty. This report describes a software package which implements the analysis procedure. The software package provides a quick and flexible means of determining in advance of programming the stability of proposed partitioning schemes for large or small-sized problems. The method is applicable for certain classes of systems, viz those which can be linearized about a current state of motion. This can, however, be realized for a wide variety of systems, since it is not required to obtain an accurate simulation of system behaviour, only to approximate the speed of response sufficiently well for the purposes of stability analysis.
