Subject [jira] [Created] (MATH-1430) Singularity check in QRDecomposition
Date Fri, 25 Aug 2017 10:23:00 GMT
Gilles created MATH-1430:
----------------------------

             Summary: Singularity check in QRDecomposition
                 Key: MATH-1430
                 URL: https://issues.apache.org/jira/browse/MATH-1430
             Project: Commons Math
          Issue Type: Improvement
    Affects Versions: 3.6.1
            Reporter: Gilles
            Priority: Minor
             Fix For: 4.0


In class {{o.a.c.m.linear.QRDecomposition}}, the singularity check seems not to be robust
enough to catch some (numerically) singular matrices.
