A preconditioning technique of Gauss--Legendre quadrature for the logarithm of symmetric positive definite matrices

Fuminori Tatsuoka, Tomohiro Sogabe, Tomoya Kemmochi +1

This note considers the computation of the logarithm of symmetric positive definite matrices using the Gauss--Legendre (GL) quadrature. The GL quadrature becomes slow when the cond…
