Characterization of the subdifferential of some matrix norms
TL;DR: In this article, a characterization of the subdifferential of matrix norms from two classes, orthogonally invariant norms and operator (or subordinate) norms, is given for some special cases.
Journal ArticleDOI
Computing the numerical radius
TL;DR: A simple algorithm is presented for computing the numerical radius of a complex matrix based on the power method for finding the maximum modulus eigenvalue of a Hermitian matrix.

Estimating Hadamard operator norms, with application to triangular truncation
TL;DR: In this paper, the power method was used to estimate Hadamard operator norms, and its application to the problem of finding the norm of the triangular truncation operator was considered.
