|svd || - singular value solver
|oneside || - boolean flag indicating if the method is one-sided or not

|-svd_lanczos_oneside <boolean> || - Indicates the boolean flag
By default, a two-sided variant is selected, which is sometimes slightly
more robust. However, the one-sided variant is faster because it avoids
the orthogonalization associated to left singular vectors. It also saves
the memory required for storing such vectors.
