Description
            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 ill-conditionned.
