Map, which is a much-scaled-down Matlab version of the java. 1 The Definition of Chaos A chaotic system in mathematics can roughly be defined as a system of ODE's that shows extreme sensitivity to initial conditions. Search Search. For further MRI processing functions, see the matlab image processing toolbox, the SPMtoolbox for matlab, and the FSLtools (in c/c++ with source code available). worldmap uses tightmap to adjust the axes limits around the map. We justify the introduction of the T ω’s by reminding the reader that conjugate maps share dynamical properties. The coding technique to handle this sort of scatter-plot at speed is to avoid calling the graphics library functions from within the loops but just use Python's built-in "lists" to hold the plotting surface, and only call the graphics library when the whole image is complete and ready for output. A more precise definition is for a system to be chaotic is must show sensitivity to initial conditions, it must be. I will look at entries up through (was: Sunday, November 27, 2011) Wednesday December 14, 2011 and announce the winner (the one whose plot I find most interesting) shortly after that.
