[Octave-bug-tracker] [bug #43728] document / warn about integer range multiplied with floating point scalar

[Markus Appel]

Follow-up Comment #5, bug #43728 (project octave):

I don't agree that this is only "incorrect documentation" ... since the
behaviour is not matlab-compatible. Say you create two grids in Matlab
(R2014b) with range times scalar and then use intersect to find common grid
points:

>> x=(-3:1)*0.1;
>> y=(-2:2)*0.1;
>> intersect(x,y)

ans =

   -0.2000   -0.1000         0    0.1000


while octave gives:


>> x=(-3:1)*0.1;
>> y=(-2:2)*0.1;
>> intersect(x,y)
ans = 0


Using brackets [] instead of parenthesis () is indeed what I meant to do in
the first place, and it gives the same result in both octave and Matlab.
