Comment #3 on issue 1421 by jochen.voss: QRdecomposition fails for some matrices http://code.google.com/p/sympy/issues/detail?id=1421
By the way, the algorithm looks like Gram-Schmidt orthonormalisation to me. Is this right? If so, the current implementation of QRsolve would probably not be "more stable than the LUsolve method" as currently advertised in the QRsolve docstring. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
