Editing GNU Octave (section)

===Syntax compatibility===
There are a few purposeful, albeit minor, [http://octave.org/wiki/index.php?title=FAQ#Porting_programs_from_Matlab_to_Octave syntax additions] {{Webarchive|url=https://web.archive.org/web/20120426060857/http://octave.org/wiki/index.php?title=FAQ#Porting_programs_from_Matlab_to_Octave |date=2012-04-26 }}:

# [[Comment (computer programming)|Comment]] lines can be prefixed with the # character as well as the % character;
# Various [[C (programming language)|C-based]] operators [[Increment operator|++]], [[Decrement operator|--]], [[Augmented assignment|+=]], *=, /= are supported;
# Elements can be referenced without creating a new variable by cascaded indexing, e.g. [1:10](3);
# [[String (computer science)|String]]s can be defined with the double-quote " character as well as the single-quote ' character;
# When the variable type is [[Single-precision floating-point format|single]] (a single-precision floating-point number), Octave calculates the "[[mean]]" in the single-domain (MATLAB in [[Double-precision floating-point format|double-domain]]) which is faster but gives less accurate results;
# Blocks can also be terminated with more specific [[Control structure]] keywords, i.e., endif, endfor, endwhile, etc.;
# Functions can be defined within scripts and at the Octave prompt;
# Presence of a do-until loop (similar to [[Do while loop|do-while]] in C).
