ON COMPUTATION OF MATRIX LOGARITHM
Nagwa Sherif, Ehab Morsy · Journal of applied mathematics & informatics · 2009
In this paper we will be interested in characterizing and com- puting matrices X 2 C n×n that satisfy e X = A, that is logarithms of A. The study in this work goes through two lines. The first is concerned with a theoretical study of the solution set, S(A), of eX = A. Along the sec- ond line computationalapproachesare considered to compute the principal logarithm of A, LogA.
