[jira] [Created] (MATH-1497) Performance issue with SVD calculation

Sudheer created MATH-1497:
-----------------------------

             Summary: Performance issue with SVD calculation
                 Key: MATH-1497
                 URL: https://issues.apache.org/jira/browse/MATH-1497
             Project: Commons Math
          Issue Type: Improvement
    Affects Versions: 3.3
            Reporter: Sudheer
         Attachments: Snapshot.jpg

We use SingularValueDecomposition(RealMatrix) and getSolver() methods.

This seems to be taking time for large matrices, refer to attached picture.

Example:925*161

I have referred to release notes of the library, It seems there are no major changes related to SVD.

 

Is there any way to improve performance,
