ut V) and V'*V = I (or V'*B*V = I if an
inner product matrix B has been specified with <A HREF="../BV/BVSetMatrix.html#BVSetMatrix">BVSetMatrix</A>()).
<P>
If V has leading columns, then they are not modified (are assumed to be already
orthonormal) and the leading columns of R are not referenced. Let the
decomposition be
<PRE>
   [ V01 V02 ] = [ V1 V2 ] [ R11 R12 ]
                           [  0  R22 ]
</PRE>

then V1 is left unchanged (equal to V01) as well as R11 (it should satisfy
V01 = V1*R11).
