    initial v1  
    2626ZeroDivisionError: Rational division by zero
    2727}}}
     28
     29Patch summary:
     30
     31  * Original Gram-Schmidt has been adjusted to raise an error on linearly dependent input.
     32
     33  * Free module version of original Gram-Schmidt was used just one place, and it has been referenced directly, rather than through the matrix version.
     34
     35  * Matrix version is totally rewritten, building on QR factorizations as possible to get orthonormal bases.  Linearly dependent subsets should be handled properly now.  Return format has, by necessity, changed.
     36
     37  * The "noscale" helper method is reminiscent of the old code, but written in a column-oriented QR style.
