We have a question about the SVD matrix used with integers values (int,
long) : JacobiSVD returns almost only 0 values for m_matrixU, m_matrixV
and m_singularValues. Is it a choosen behavior with integers or it is
the real result of the SVD ? Does our BDCSVD must have a specific
behavior with integers types?

`Actually, I would suggest raising a compile error if the scalar type
``does not support required operations such as sqrt, division, etc.
``It would also make no sense to calculate an SVD with rational
``coefficients (however, LU with rationals would make sense).
`

`Had this been the original purpose of the meta programming, which was
``cleaned up here?
