octave-common 4.2.1-2build1 (armhf binary) in ubuntu bionic

 Octave is a (mostly Matlab (R) compatible) high-level language, primarily
 intended for numerical computations. It provides a convenient command-line
 interface for solving linear and nonlinear problems numerically.

 Octave can be dynamically extended with user-supplied C++ files.

 This package provides the architecture-independent files (Octave scripts
 and other helper files).
