Octave is written in C++ using the C++ standard library.Īcceleration with OpenCL or CUDA is also possible with use of GPUs. ![]() For example, Octave was used on a massive parallel computer at Pittsburgh Supercomputing Center to find vulnerabilities related to guessing social security numbers. In addition to use on desktops for personal scientific computing, Octave is used in academia and industry. Publication of Octave 7.1.0 (QT5 preferred), improved graphics backend and matlab function compatibility Publication of Octave 6.2.0 (QT5 preferred), Bugfix, improved matlab syntax support Publication of Octave 6.1.0 (QT5 preferred, Qt 4.x deprecated for remove in 7) Publication of Octave 5.2.0 (QT5 preferred) Publication of Octave 5.1.0 (QT5 preferred, Qt 4.8 minimum), hiDpi support Version 4.4.0 (new Goal for GUI QT Toolkit, the FLTK toolkit is not deprecated and there is no schedule for its removal - while no longer prioritized) Version 4.0.0 (stable GUI and new Syntax for OOP) Publication of Octave 3.8.0 (experimental GUI) Development history Timeġst Publication (Version 1.0.0 to 1.1.1) Ģnd Publication (Version 2.0.x) with Windows Port ( Cygwin) Levenspiel was known for his ability to perform quick back-of-the-envelope calculations. The program is named after Octave Levenspiel, a former professor of the principal author. Version 7.1.0 was released on Apr 6, 2022. The first alpha release dates back to 4 January 1993 and on 17 February 1994 version 1.0 was released. At first it was intended to be a companion to a chemical reactor design course. 11 Comparison with other similar software.6.1 Command and variable name completion.Finally, comments can be used to aid in debugging, as explained in Debugging M Files. Such text is often found at the end of an M file though also can be found at the beginning. MATLAB will output the comments leading up to the function definition or the first block of comments inside a function definition when you type:Īll of MATLAB's own functions written in MATLAB are documented this way as well.Ĭomments can also be used to identify authors, references, licenses, and so on. ![]() It is common and highly recommended to include as the first lines of text a block of comments explaining what an M file does and how to use it. ![]() % Calculate average velocity, assuming acceleration is constant Doing this is a good idea both for yourself and for others who try to read your code. E.g.Ĭomments are useful for explaining what function a certain piece of code performs especially if the code relies on implicit or subtle assumptions or otherwise perform subtle actions. */ in languages like C or C++, via the % contains any other text (except white spaces). MATLAB also supports multi-line comments, akin to /*. Select the code you wish to comment or uncomment, and then press Ctrl-R ( ⌘-/ for Mac) to place one '%' symbol at the beginning of each line and Ctrl-T ( ⌘-T for Mac) to do the opposite. There are two useful keyboard shortcuts for adding and removing chunks of comments. In the MATLAB Editor, commented areas are printed in green by default, so they should be easy to identify. The % character itself only tells the interpreter to ignore the remainder of the same line.
