| 215 | 42 ### Syntax Examples |
| 43 | |
| 44 The Octave syntax is largely compatible with Matlab. | |
| 45 The Octave interpreter can be run in | |
| 46 <a href="#" data-open="guiModal">GUI mode</a>, as a console, | |
| 47 or invoked as part of a shell script. | |
| 48 More Octave examples can be found in | |
| 49 [the Octave wiki]({{ site.wiki_url }}/Using_Octave). | |
