Yes, indeed, that's very interesting:

a
-0.08936    0.971
-0.5195  -0.1061
 0.3311  -0.4731

matrixU
-0.8752  -0.2161        0
-0.009971   0.9026        0
 0.4837  -0.3723        0

sigma
 1.105       0
     0  0.5873
     0       0

matrixV.transpose()
 0.2205  -0.9754
-0.9754  -0.2205
This unit test is really very insufficient. It should at least have
checked that U is unitary.
