About this app

This really is GNU Octave running on your device. It is full featured and professionally supported.

This lets you run Octave / Matlab code on your phone (not the cloud) and without restrictions.

About Octave:
GNU Octave supports a powerful mathematics-oriented syntax with built-in 2D/3D plotting and visualization tools. It features a high-level programming language, primarily intended for numerical computations. Octave helps in solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with MATLAB. It may also be used as a batch-oriented language. It has too many features to list here, but you can check out the project page for more information: https://www.gnu.org/software/octave/

How to use this Octave Android app:
If using the terminal, you just start typing commands as you see fit.
If using the graphical interface, use it just like normal. But here are some specifics to the Android interface.
* Tap with one figure to left click.
* Move mouse by sliding around one finger.
* Pinch to zoom.
* Press and hold and then slide one finger to pan (useful when zoomed in).
* Slide two fingers up and down to scroll.
* If you want to bring up a keyboard, tap on the screen to get a set of icons to appear and then click the keyboard icon.
* If you want to do the equivalent to a right click, tap with two fingers.
* If you want to change the desktop scaling, find the service android notification and click the settings. You have to stop and restart the app after changing this settings for it to take effect.
This is all easier to do on a tablet and with a stylus, but it can be done on a phone or using your finger as well.

To access files from the rest of Android, there are many useful links in your home directory (/home/userland) to places like your Documents, Pictures, etc. No need to import or export files.

If you don't want to, or cannot pay the cost of this app, you can run Octave via the UserLAnd app.

This app is not created by the main GNU Octave development team. Instead it is an adaptation that allows the Linux version to run on Android.

Ratings and reviews

I haven't used the terminal much so this review is mainly concerning the GUI. This is basically the same as the PC software. Quite tricky to use with a touchscreen but works well overall. I'm now using a bluetooth keyboard/trackpad which is a huge improvement. It's nice to have these capabilities on-the-go and means I wont need to carry my laptop as often. It works suprisingly fast as well, possibly even faster than my laptop which I don't understand. Well worth the money IMO.

Would not work on Android 13, probably permissions. Worked on older device. This is not really native, it installs over 1 GB to make up a mini-Linux distribution and run VNC. It is the full Octave product but via this workaround. I did not find this suitable and uninstalled, however I will not refund in order to at least minimally support the dev who has put a lot into this. Hoping one day for a native Android version.

Come on guys! Do better! I selected the graphics interface and was instructed to select Next, there is NO Next button! I am expecting at least a similar UI as on Windows and as shown on the app's Google Play page. I want to load a script or create one. How and where can I do that??! I am running Android 13 on a Samsung Galaxy phone. I'm a fan of Octave on Windows, but this is disappointing. Before I request a refund, can someone give clear guidance on how to get started please, ASAP. Thanks.
