[Octave-bug-tracker] [bug #59718] Broadcasting does not work with sparse matrices

[Rik]

Update of bug #59718 (project octave):

                Category:         Octave Function => Interpreter            
              Item Group: Unexpected Error or Warning => Matlab Compatibility 
 
                  Status:                    None => Confirmed              
                 Summary: Workaround for operators involving a sparse matrix
and broadcasting => Broadcasting does not work with sparse matrices

Follow-up Comment #2:

Changing the Category to "Interpreter" and the Item Group to "Matlab
Compatibility" since Matlab does offer broadcasting between sparse and full
matrices.

As jwe mentioned, this is probably a big project in the end because the
internals of Octave which implement broadcasting need to be overhauled at the
same time.

This would be a useful project as we have different ways of implementing
broadcasting (through the interpreter or directly through a function like
bsxfun) and these different methods mean parallel code to maintain and they
exhibit different performance (which is really wacky).
