Numerical algorithms for polynomial matrices for TI-89
Author: Stefko Petr
In this diploma thesis I designed a package of functions for polynomial matrices for a calculator TI-89 produced by Texas Instruments Inc. This package includes a set of functions for computing with polynomial matrices and a library of auxiliary functions. This thesis also brings a description of calculator TI-89 and its hardware versions, history of operation system AMS (Advanced Mathematical Software) and its limitations, kernel programs which remove AMS limitations. Explain tagged representation of numbers, variables and expressions on the Expression Stack. At the end of this diploma thesis is simple example demonstrating use of the polynomial functions for a simple controller design via pole placement. This thesis is concluded by a discussion of suitability of the calculator for education in control theory.
