annotate liboctave/array/CSparse.cc @ 17691:8a54a481ecb5
Massive speed improvement in sparse min/max functions for calls like
'max(s,[],2)' (bug #40268)
* dSparse.cc (SparseMatrix SparseMatrix::max (Array<octave_idx-type>&, int)) :
Remove triple loop by using a local buffer
(SparseMatrix SparseMatrix::min (Array<octave_idx-type>&, int)) : ditto
* CSparse.cc (SparseComplexMatrix SparseComplexMatrix::max (
Array<octave_idx-type>&, int)) : Remove triple loop by using a local buffer
(SparseComplexMatrix SparseComplexMatrix::min (Array<octave_idx-type>&,
int)) : ditto
