eig( [ 0 2 5 ; 1 0 0 ; 0 1 0 ] ) % roots of p ans = 2.094551481542328 + 0.000000000000000i -1.047275740771163 + 1.135939889088928i -1.047275740771163 - 1.135939889088928i

Maybe this does not count as a “zero finder” because it computes all the roots of a polynomial.

I mentioned a example taken from Todd’s 1979 book “Numerical Mathematics. Vol. 1: Numerical Analysis”. Todd liked to include “bad examples”, to temper the tendency to rely on numerical experience. One such example involves a computer experiment used to “show” that the harmonic series converges.

This prompted David Malone (Maynooth University) to write a neat note “To what does the harmonic series converge?” (rish Math. Soc. Bulletin Number 71, Summer 2013), which might be of interest to readers of this blog.

]]>Please check this :”We named the MATLAB verion fzero. Here is the textbook version, fzerotx, from Numerical Computinng with MATLAB. This is not all of the MATLAB fzero. In my next blog post I will deal with the need to know an interval on which the function changes sign.”, “verion”, “Computinng”.

That said, great post!
