            The goal of this toolbox is to provide a collection of 
test matrices. 

Some of these matrices appears in specific applied mathematics problems. For
example, the Van Der Monde matrix appears in polynomial interpolation. Another
example is the Hilbert matrix, which arises in the least squares approximation
of arbitrary functions by polynomials.

These test matrices can also be used to experiment with linear algebra
algorithms, such as the resolution of systems of linear equations or the
eigenvalue problem. 

For some of these test matrices, the exact eigenvalues, condition number or
invert is known. For example, the Hilbert matrix is symetric positive definite.
Another example is Frank's matrix, which has a unit derminant, but is
