Input Parameters
| svd | - singular value solver context
|
| its | - iteration number
|
| nconv | - (unused) number of converged singular triplets so far
|
| sigma | - (unused) singular values
|

Note
Works only for solvers that use a DS of type GSVD. The printed information corresponds
to the maximum of the condition number of the two generated bidiagonal matrices.
