Subject [jira] [Created] (MATH-1191) QRDecomposition decompose and performHouseholderReflection methods ignore matrix parameters
Date Sat, 10 Jan 2015 16:10:36 GMT
Phil Steitz created MATH-1191:
---------------------------------

             Summary: QRDecomposition decompose and performHouseholderReflection methods ignore
matrix parameters
                 Key: MATH-1191
                 URL: https://issues.apache.org/jira/browse/MATH-1191
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.3
            Reporter: Phil Steitz
             Fix For: 4.0, 3.4.2


The protected decompose and performHouseholderReflection methods in QRDecomposition act on
the qr matrix set by the constructor, not whatever matrix is supplied as actual parameter.
 For 3.x, the javadoc should be updated to indicate that the actual parameter is ignored.
For 4.0, the parameters should be removed.
