Properties and computations of matrix pseudospectra
The theory of numerical linear dependence, as described by \textit{X.-C. He} [Numer. Math., Nanjing 1, 11--19 (1979; Zbl 0425.65027)], is used to give an alternative definition of the pseudospectrum of an \(m\times n\) matrix. Some properties of pseudospectra are explored and an algorithm for the computation of pseudospectra is given.
