This is a Sage optional package containing part of my own research code. It contains modules on digital geometry, combinatorics, combinatorics on words, multidimensional continued fraction algorithms, matrix cocycles, languages, substitutions, bispecial factors, double square tiles, Oldenburger sequence, Joyal bijection, Dyck word in 3D, Markov transformations, some graphs and matrix methods, tikzpictures.

Installation:

sage -pip install slabbe

Usage:

sage: from slabbe import *

Version 0.3b2 includes a new module for diophantine approximations, random point generation inside polytopes, analyzing sage building time, and many improvements to previous modules.

Version 0.3b1 is now a Python package available in the Python Package Index (PyPI). It was migrated from the previous sage optional spkg old-style format. It also adds code to deal with bispecial factors, some new methods of graphs, substitutions and matrices.

slabbe-0.2.spkg (documentation) provides modules on multidimensional continued fraction algorithms, matrix cocycles, languages and tikzpictures.

Installation:

sage -p http://www.slabbe.org/Sage/slabbe-0.2.spkg  # sage-6.9 or newer
sage -i http://www.slabbe.org/Sage/slabbe-0.2.spkg  # sage-6.8 or earlier

slabbe-0.1.1.spkg fixes a bug with gcd import error.

Installation: sage -i http://www.slabbe.org/Sage/slabbe-0.1.1.spkg

slabbe-0.1.spkg (documentation) contains modules on digital geometry, combinatorics on words and more.

Installation: sage -i http://www.slabbe.org/Sage/slabbe-0.1.spkg
