>          Issue Type: Bug
>          Components: Math
>    Affects Versions: 0.7
>            Reporter: Ted Dunning
>            Priority: Blocker

>
> There are two issues, one benign and one huge.  The benign issue is that all 
> references in MatrixView.viewPart to the constant 0 got incorrectly replaced 
> by ROW.
> The big issue is that origin.clone() is used instead of this.origin.clone().  
> This causes double incrementing and an index error for some args.  I have 
> added a test and will commit shortly.
