GERSHGORIN DISK FRAGMENT UNTUK MENENTUKAN DAERAH LETAK NILAI EIGEN PADA SUATU MATRIKS

Abstract

Gershgorin disk method is an analytic technique available for determining the location of eigenvalues. In this article, we discuss the method of Gershgorin disk fragment by narrowing the location of eigenvalues obtained using the method of Gershgorin disk. By knowing the narrowed location of eigenvalues, better initial guesses to determine the numerical estimates can be obtained.
