Programming manual for IDENT, a parametric and nonparametric linear systems identification package.

This document is intended to provide helpful information to anyone wishing to adapt IDENT for use on a computer other than an LSI-11, or on an operating system other than RT-11 version 4, or with different data structures. An overall picture of IDENT is provided by Tables 1-7, in which the common variables and the overlay structure are outlined. The function of each subroutine is noted briefly. The main program establishes parameters for the program run. Part of it is concerned with specific data structures or with RT-11 functions and would probably require change. The subroutine, COMMAN, is called by the main program for each set of input and output data. COMMAN is the calling routine for all of the commands processed by IDENT and thus must be located in the root segment. Also provided in this manual are linking instructions, a list and description of RT-11 functions used in IDENT. A discussion of the structure of a main program is provided. Also, the means by which the parameter estimator's convergence rate could be altered by some minor program changes is outlined.
