Sign differences amoung QR solutions.
...but the property X = QR holds in all cases. My question is are there any gotchas (similar to the sign for tan) that I need to be aware of when using the results of a QR decomposition? With the sign differences it seems that there could be many possible decompositions for one matrix depending on the algoithem. Thank you. Kevin
