Computation of the exponential function of matrices by a formula without oscillatory integrals on infinite intervals
Masato Suzuki, Ken'ichiro Tanaka
We propose a quadrature-based formula for computing the exponential function of matrices with a non-oscillatory integral on an infinite interval and an oscillatory integral on a fi…

The Nearest Graph Laplacian in Frobenius Norm
Kazuhiro Sato, Masato Suzuki
We address the problem of finding the nearest graph Laplacian to a given matrix, with the distance measured using the Frobenius norm. Specifically, for the directed graph Laplacian…
