invol

a <code>n</code>-by<code>n</code> involutory matrix and ill-conditioned.
It is a diagonally scaled version of a Hilbert matrix.

Generates a variety of structured test matrices commonly used in numerical linear algebra and computational experiments. Includes well-known matrices for benchmarking and testing the performance, stability, and accuracy of linear algebra algorithms. Inspired by 'MATLAB' 'gallery' functions.
