comparison liboctave/dSparse.cc @ 13030:b646413c3d0e
Make operators do smarter sparse conversions on permutation matrices.
* Sparse.cc (Sparse<T>::Sparse): New templated ctor, plus two instantiations.
* Sparse.h (Sparse<T>): Declare new ctor.
* MSparse.h (MSparse): Give this class a PermMatrix ctor.
* boolSparse.h (BoolSparseMatrix): Ditto.
* dSparse.cc: Refactor PermMatrix ctor, moved into common parent class.
* dSparse.h (SparseMatrix): Ditto.
* op-pm-sm.cc: Declare and install smarter permutation matrix operators.
* ov-perm.cc (octave_perm_matrix): Declare new virtual function override.
* ov-perm.cc (sparse_bool_matrix_value): Override this virtual function.
