[Octave-bug-tracker] [bug #31823] floor/ceil caching causing incorrect behavior when concatenating

[John W. Eaton]

Update of bug #31823 (project octave):

                  Status:               Need Info => Invalid                
             Open/Closed:                    Open => Closed

Follow-up Comment #4:

I suspect your problems is the spaces before the +floor and +ceil in the
expression


-Wx = [  n*(floor(Gx)-1)+floor(Gy) , ...
            n*(ceil(Gx)-1) +floor(Gy) , ...
            n*(floor(Gx)-1)+ceil(Gy)  , ...
            n*(ceil(Gx)-1) +ceil(Gy)  ];


Octave parses these as separate elements, not a binary addition.  See the
explanation here:

If this is not the problem, then reopen the bug report and tell us the values
of m and n in the call to your function so that we can reproduce the error..
