RTB codes for Fall 2006

This directory contains the Matlab functions (revised on November 27, 2006 to work in Matlab, since the original versions used a number of octave-specific extensions) related to the supplement on A robust method for finding characteristic polynomials. The files are:

• polyf.m The basic routine for generating the characteristic polynomial and the matrices that drive the algorithm.
• syndivf.m A synthetic division program to evaluate a matrix polynomial.
• shift.m A routine that uses synthetic division to replace the array of coefficients of P(x) with those of P(c+y).
