Testing the library is a good way to learn how it works, and minimises
any downside in terms of breaking things.

For example, something that would be useful is to write a program that
exhaustively checks different matrix decompositions such as QR,
SVD,... by multiplying the results back together and seeing if they
match the original matrix (with errors).  

It is fairly easy to write a program that will loop through all NxN
matrices with integer elements in a range [a,b], and then use it to
check all matrices with size 2x2, 3x3, 4x4, ... etc.  Personally I
have only tested up to 4x4 with the coefficients -1,0,+1 so there is
room for more work in this area.
