Follow-up Comment #12, bug #38149 (project octave):
Matlab is being a bit opaque, as usual:
>> version
ans =
7.9.0.529 (R2009b)
>> te = regexp ('abc', 'abc(z)?', 'tokenExtents');
>> typeinfo (te)
??? Undefined function or method 'typeinfo' for input arguments of type
'cell'.
>> celldisp (te)
te{1} =
4 3
>> te{:}
ans =
4 3
>> te[:]
??? te[:]
|
Error: Unbalanced or unexpected parenthesis or bracket.
Here is the result of "help disp" in Matlab:
>> help disp
DISP Display array.
DISP(X) displays the array, without printing the array name. In
all other ways it's the same as leaving the semicolon off an
expression except that empty arrays don't display.
If X is a string, the text is displayed.
=====================
This not quite the way disp() works in Octave, or actually
the way it seems to work in Matlab.
