[ojAlgo-user] Eigenvalue Decomposition Problem

[<mi...@vt...>]

I am trying to compute the eigenvectors of a matrix. For some reason several
java matrix packages (Jama, Colt, Mtj) compute eigenvectors (V) for this matrix
(A) that do not satisfy the equation AV = XV and therefore are incorrect. As a
result of this problem, I am trying to use the ojalgo package to compute the
eigenvectors to see if its results are any different. However, I am relatively
new to OO programing and I can't figure out how to use the matrix decomposition
interfaces.

The matrix is:
9.28 0.48 -2.72 1.28 -8.32
4.48 0.68 -6.52 2.48 -1.12
-8.32 -0.12 8.68 -2.32 2.08
7.68 0.88 -10.32 3.68 -1.92
-13.12 -1.92 10.88 -5.12 9.28

1.
How do I use the ojgalgo matrix decomposition interfaces or where I can find
an example of thier use?

2.
Why is this matrix such a problem for the other java packages?

Thank you in advance for any help that you can provide.
