Update of bug #59521 (project octave):
Item Group: Incorrect Result => Matlab Compatibility
Status: None => Works For Me
Open/Closed: Open => Closed
_______________________________________________________
Follow-up Comment #1:
Regardless of expectations, Matlab returns 4 for the sample code. Since
Octave desires to be Matlab-compatible, we also need to return 4.
The issue is that the anonymous function is not a transparent passthrough of
the input to the output.
f = @(x) x;
It looks like a passthrough for ordinary values like 1.1 or "string". But it
is not, or you could write a while loop like this:
f(while i < 5)
i++;
endwhile
In this case, while the interpreter doesn't throw an error, "f(end)" always
returns the value 1.
