WebFor negative and complex numbers z = u + i*w, the complex square root sqrt (z) returns sqrt (r)* (cos (phi/2) + 1i*sin (phi/2)) where r = abs (z) is the radius and phi = angle (z) is … WebFeb 1, 1998 · This paper presents two parallel algorithms for the solution of a polynomial equation of degree n, where n can be very large. The algorithms are based on Graeffe's root squaring technique implemented on two different systolic architectures, built around mesh of trees and multitrees, respectively. Each of these algorithms requires O (log n) …

INTRODUCTION In many real-time applications, e.g., automatic control, digital signal processing, etc., we often need fast extraction of the roots of a polynomial equation with a very high degree. What is today often called the Graeffe Root-Squaring method was discovered independently by Dandelin, Lobacevskii, and Graeffe in 1826, 1834 and 1837. A 1959 article by Alston Householder referenced below straightens out the history. The idea is to manipulate the coefficients of a polynomial to produce a … See more Here is an elegant bit of code for producing a cubic whose roots are the squares of the roots of a given cubic.

Webroot squaring is proposed. He seems to consider it important that although Lobacevskil's Algebra [6] bears the date 1834, it was actually in the hands of the censor in 1832. But he builds his case upon the assertion that Dandelin's paper was concerned primarily with Newton's method, and that root squaring is WebIt is been said that Graeffe's method determines all the roots of an algebraic equation real and complex, repeated and non-repeated simultaneously. In this study, it is said that this statement is ...

The process is repeated several times to obtain the desired separation.
