Re: Make Octave behave more like Matlab

oops, there was a bug in my example, here is the correct one:

color = 'green';
switch color
case 'red'
disp('It is red.');
otherwise
disp('It is not red.');
end
It is not red.

Here is what I get if I try to use double quotes:

color = "green";
??? color = "green";
           |
Error: The input character is not valid in MATLAB statements or expressions.

Do you know what version of Matlab is being used? I'm using 7.3 and it
does not require commas after case statements (nor can I recall any
version that did since I started using it):

ans =

7.3.0.298 (R2006b)

>> color = 'green';

end
It is not red.

As for the quotes issue, why not use single quotes in octave?
