we just published our new Android app: Anoc Octave Editor
It's a GUI for Octave (= Matlab clone) that allows you to create .m files and perform calculations and generate plots on a dedicated server and display the result.
It currently supports two modes:
1. Local: Store all .m files, projects and generated plots locally on your device
2. Remote: All .m files and projects are synchronized with your account at verbosus.com
