OpenBLAS is installed by default, and this method provides much better performance compared to Octave installed inside a GNU/Linux distro running in Termux. By default, Octave only plots with ASCII characters in the terminal. | |||
For graphical plots, [https://wiki.termux.com/wiki/Graphical_Environment#Desktop_environment_.28XFCE.29 install] a graphical environment like xfce, and use octave with a vnc server. Only the graphics toolkit `gnuplot` is known to work in this method. | |||

=== Via some GNU/Linux distribution === | |||
Inside Termux in Android, you can install a Linux distribution like Debian, Ubuntu, Arch or Alpine. Note that Alpine consumes relatively less disk space. Octave can be installed as described in [[Octave for GNU/Linux]] from the distribution's respective package manager. | |||
To use Octave's graphical capabilities, one needs to install a desktop environment, and a VNC server in the GNU/Linux distro, and one also needs to install a separate VNC viewer app in the Android phone (can be installed from Play Store/F-Droid). On many android devices, only the graphics toolkit "gnuplot" is known to work. Several apps (e.g. [https://github.com/EXALAB/AnLinux-App Anlinux], [https://andronix.app/ Andronix]) are available to easily install the Linux distribution of your choice, and setting up the desktop environment. Refer to the [https://docs.andronix.app/vnc/vnc-basics Andronix docs] for an overview of setting up the VNC server. | |||
'''Optimizing performance''': Installing [https://github.com/xianyi/OpenBLAS/wiki/Precompiled-installation-packages/ OpenBLAS] (with the distribution's package manager) to replace the system's BLAS libraries may tremendously increase the performance of Octave. | |||
