Matrix Market
A repository of matrix test data for use in comparative studies of algorithms. The matrices have been taken from problems in linear systems, least squares, and eigenvalue calculations in a wide variety of scientific and engineering disciplines. Includes search for matrices by size, mathematical properties, and keywords.

Eigenvalue analysis of non-hermitian matrices and operators can be misleading: Predictions often fail to match observations. Specifically, trouble may arise when the associated sets of eigenvectors are ill-conditioned with respect to the norm of applied interest. In the case of the familiar Euclidean or 2-norm, this means that the matrix or operator is non-normal, and the eigenvectors are not ...
