Comment:
v2 patch adjusts the tests to not rely on exact values in the unitary
matrix, nor above the diagonal in the upper-triangular matrix. It adds a
few more checks on the diagonal entries, which are the eigenvalues of the
matrix. There are also a couple of new checks on the 2-norm of the
similar matrices, one for the real case and one for the complex case.
This passes tests on my desktop (Ubuntu, i7-2600) and on sage.math.
Jason - would you mind testing this on a Mac before we turn it loose?
