[Bug-gsl] bug report gsl_multifit_wlinear_svd

[Mezger Anton-Chr.]

The introduction of balancing the matrix does not seem to account for a
rank reduction. The routine gsl_multifit_wlinear_svd performs well when
no rank reduction is taken place. When the rank gets reduced however the
results are wrong and when the balancing code is taken out the results
are correct. Do I see this correctly and when yes is it possible to
correct it ?

 

Best Regards
