Follow-up Comment #4, bug #36562 (project octave):

Rik :


>> Msparse = sparse ([1 0; 0 3]);
NaN .* Msparse

ans =

   (1,1)      NaN
   (2,1)      NaN
   (1,2)      NaN
   (2,2)      NaN


so your solution does not seem to be compatible.

Anyway, I wouldn't like that solution even if it were compatible
as any error in filling the elements of a large sparse matrix would result in
out-of-memory.
