| 215 | 40 ### Syntax Examples |
| 41 | |
| 42 The Octave syntax is largely compatible with Matlab. | |
| 43 The Octave interpreter can be run in | |
| 44 <a href="#" data-open="guiModal">GUI mode</a>, as a console, | |
| 45 or invoked as part of a shell script. | |
| 46 More Octave examples can be found in | |
| 47 [the Octave wiki]({{ site.wiki_url }}/Using_Octave). | |
