Details:
Hello, I am working on porting MATLAB to Octave, normally | and & will short
circuit in if() statements just like MATLAB. However if a function with a
negative is used like ~exist(),~strcmp() or ~isempty(), the statements do not
seam to short circuit like MATLABs do. ~= and the functions without ~, however
do work. Example: (Octave/Matlab)
%From an empty workspace
%Octave
if ~exist('a','var') | b == 2
disp('TRUE');
end
error: 'b' undefined near line 1 column 27
%Matlab
if ~exist('a','var') | b == 2
disp('TRUE');
end
TRUE
Setting do_braindead_shortcircuit_evaluation doesn't seam to change anything.
Thank you for your help,
Andrew
