Mixed, Componentwise, and Structured Condition Numbers
Israel Gohberg, I. Koltracht · SIAM Journal on Matrix Analysis and Applications · 1993
Mixed, componentwise, and structured condition numbers for continuous maps in finite-dimensional spaces are introduced. For differentiable maps, convenient formulas for the estimation of such condition numbers are given and illustrated on the example of Toeplitz matrices. Applications to Vandermonde matrices are also presented.
