Luc Maisonobe resolved MATH-1191.
---------------------------------
Resolution: Fixed
Fix Version/s: (was: 3.4.2)
3.5
Fixed in git repository, for both 3.5 and 4.0.
Instead of removing the parameters, they are now properly used. It does not
really change anything since the parameter passed was already the same matrix.
> 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, 3.5
>
>
> 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. Alternatively, implementations could be
> changed to act on the arguments.
