Hi Carlo,
I've looked at the "triangular" example.
So, from the .texi and .cc files by myself, I've learned:
- the need for using mlock() in the oct-file (commit'ed the change)
- that the 'triangular' example does not fit completely to sparsersb:
class octave_triangular_matrix extends class octave_matrix, while
class octave_sparse_rsb_matrix extends class octave_sparse_matrix
- subsref, subsasgn, dotref are unfinished in sparsersb
- the 'print(std::ostream&...' method is incomplete: is this method
the one ensuring the cool output paging capability in Octave ?
- assignments, conversions: these are important but a bit obscure to
me now; however there is no hurry with them I would say, as they
are not in the "critical" features list one would expect from
sparsersb ;
Since I would prefer to follow a principle of caution, I would not
implement the mentioned missing features, until I get positive responses
(so, octave-dev's peple help is critical here) about current sparsersb's
stability, error reporting, robustness for installation and (shared
memory parallel, optimized) core operations (e.g.: matrix creation,
multiplication, triangular solution).
