摘要: Summary The existing algorithms for computing the minimal Gersgorin set are designed small and medium size (irreducible) matrices based on Perron root computations coupled with bisection method sampling techniques. Here, we first discuss drawbacks of methods present a new approach modified Newton's to find zeros parameter dependent left-most eigenvalue Z-matrix special curve tracing procedure. The advantages presented several test examples that arise in practical applications. Copyright © 2015 John Wiley & Sons, Ltd.
