Hi, I'm finalizing unit tests for the conjugate gradient method, for which I'm using Hilbert matrices (see http://en.wikipedia.org/wiki/Hilbert_matrix). These matrices are nice because i. they are symmetric, positive definite, ii. they are ill-conditioned, iii. their inverse is known in closed-form.
I therefore implemented HilbertMatrix and InverseHilbertMatrix as RealLinearOperator. These two classes are intended for testing purposes only, but I do not want to embed them in ConjugateGradientTest, as they might be used to test other iterative solvers as well. My question is simple: where (meaning: which package) should these two classes go? Would o.a.c.math.linear (in the src/test/java directory) be suitable? Any better suggestion?
