Numerical simulations of the Klein-Gordon field with nonlinear interaction: collection of scripts for the numerical simulation of the infinite Klein-Gordon field subject to certain nonlinear interactions.
Octave basics: Very basic and brief introduction into Octave and including EPS plots from there into LaTeX.
Using Octave to prepare figures for LaTeX papers: Several examples on preparing figures (PSTEX and EPS) with Octave and using them in LaTex for PDF "powerpoint-like" presentations.
Nonlinear instability of a critical traveling wave in the generalized Korteweg -- de Vries equation: example of a PDF talk with Octave-generated pictures.
Solitary waves as global attractors for dispersive nonlinear Hamiltonian systems: example of a PDF talk with Octave-generated pictures.

bibget: a command-line front-end for MathSciNet index. Helps generating bibtex databases for LaTeX. Example:
bibget a=stein t=harmonic book 1993
returns a reference to Stein's book on Harmonic Analysis, in bibtex format.
