From the reviews:
"Explains the mathematics useful for the description of those systems, when imbedded in a mathematical framework of discrete time, and elements which take their values either in discrete or in Euclidean spaces ... . The reviewer sees two uses for the book. It could be a valuable information source for someone interested in an overall picture of the subject ... . other use would be for a reading course by a courageous student willing to reconstruct part of the material."
