A function is a mathematical expression that describes the relationship between two sets of values, typically input (x-values) and output (y-values). When the output value is zero, the corresponding ...

The ability to find the zeros or roots of a function is an essential skill in mathematics as it helps in understanding the behavior of functions, solving equations, and graphing. With the help of a ...

A method which finds simultaneously all the zeros of a polynomial, developed by H. Rutishauser, has been tested on a number of polynomials with real coefficients. This slowly converging method (the ...

This python package aims at finding poles and zeros of a meromorphic function with their multiplicities inside a closed contour in the complex plane. All the roots can be found without initial guess.

SIAM Journal on Numerical Analysis, Vol. 20, No. 5 (Oct., 1983), pp. 1023-1031 (9 pages) In this paper a scheme is presented to numerically evaluate the argument principle for a real polynomial on the ...
