Failing case of QR decomposition

Open mikera opened this issue 11 years ago • 2 comments

The following Qr decomposition case appears to fail:

[[  0 , 0 ],
 [ -1 , 0 ]]

with results

Q= [[  0.0,  1.0 ],
    [  1.0,  0.0 ]]
R= [[ -1.0,  0.0 ],
    [  0.0, -1.0 ]]

@prasant94 any thoughts you have on how to fix this much appreciated!

It seems that QR decomposition is currently ignoring the "error" case for QR decomposiotions. I think this is a problem for many cases - probably for any non-full-rank decoposotion?
