43 ### Syntax Examples |
|
|
44 |
|
|
45 The Octave syntax is largely compatible with Matlab. |
|
|
46 The Octave interpreter can be run in |
|
|
47 <a href="#" data-open="guiModal">GUI mode</a>, as a console, |
|
|
48 or invoked as part of a shell script. |
|
|
49 More Octave examples can be found in |
|
|
50 [the Octave wiki]({{ site.wiki_url }}/Using_Octave). |
