[Octave-bug-tracker] [bug #56385] operations don't compose

[anonymous]

Follow-up Comment #5, bug #56385 (project octave):

Actually, it seems this problem has not been totally fixed for all
functions... With the attached slightly augmented MyFavoriteDouble class, I
recover the same issue:


octave:1> mex myFavDouble_mex.cpp
octave:2> a = myFavDouble(2)
 
a = 
 
2.000000
 
octave:3> b = myFavDouble(3)
 
b = 
 
3.000000
 
octave:4> a:b
ans =

   2   3

octave:5> b:a
ans = [](1x0)
octave:6> myFavDouble(2):myFavDouble(3)
octave:7> myFavDouble(3):myFavDouble(2)
octave:8> c=myFavDouble(2):myFavDouble(3)
error: value on right hand side of assignment is undefined
octave:8> d=myFavDouble(3):myFavDouble(2)
error: value on right hand side of assignment is undefined


Results are properly assigned when calling the function `colon` with
pre-existing objects. But no results are assigned when the method `colon` is
called with new objects. We would expect the last four lines to reproduce the
results of lines 4 and 4... (running octave 6.0.0)
