We present the package Optimizer, aimed at constructing and optimizing general mathematical models of phenomena of versatile nature. It is written in the Matlab algorithmic language and is executed in the Matlab environment with partial functionality in Octave. The convenient visual interface and the detailed manuals are provided. The main benefit of the package is its capability to construct models of any level of complexity in a block-by-block manner. Elementary model blocks can be...

Code updated. There were a few errors in the physical model of the concentration field of secreted chemokine surrounding each cell, together with a few coding errors. All have been corrected, the model refitted, and all simulations presented in the paper repeated. Results from this corrected model are on par with the published results. See pdf file for details.

software for identifying modules in networks (e.g. "community detection"), as described in "a bayesian approach to network modularity" (physical review letters 100, 258701 (2008); http://link.aps.org/abstract/PRL/v100/e258701).

Tycho is a MATLAB package for mission analysis and ADCS applications. It is composed of four sub-packages: a) an orbits toolbox which implements basic Keplerian and generalized orbit functions (physical state to Keplerian parameters and generalized parameters, time to true anomaly, etc.). It also implements tools to design impulsive maneuvers to change any of the five applicable Keplerian parameters. A dedicated function exports orbits as .xyzv Celestia files. b) a perturbations toolbox that allows to numerically assess the effect of arbitrary perturbations by integrating Gauss equations. ...
