octave: liboctave/numeric/svd.cc annotate

annotate liboctave/numeric/svd.cc @ 22228:4afe3705ea75

svd: do not shadow member variables with local variables. * liboctave/numeric/svd.cc, liboctave/numeric/svd.h: there was no issue with current code because member variables never change after construction. Still, it's not good practice and the compilers will warn about it.
