This is latest release of the discontinued Test Matrix Toolbox by Nicholas J. Higham. From the Matrix Computation Toolbox documentation:
The Test Matrix Toolbox (last release, 1995) has been superseded by the The Matrix Computation Toolbox (first release, 2002).
Most of the test matrices in Test Matrix Toolbox have been incorporated into MATLAB in the gallery function. The new toolbox incorporates some of the other routines in the Test Matrix Toolbox (in some cases renamed) and adds several new ones.
I will be using the original Higham's work as basis for implementing missing functions in GNU Octave. That means the head of the repository will NOT be the original release, and may not be working at all. Check the initial commit (or tag v3.00) for the actual latest release of the toolbox.
While the original Test Matrix Toolbox was distributed without a license, I received permission from Professor Higham to use it under the GNU General Public License version 3 or later:

Note: I do not claim authorship of this, all respect is due to Professor Nicholas Higham, I am simply making small adjustments in order to be included in GNU Octave.
