fp-stability

A set of MATLAB functions used to calculate bifurcations and fixed point stability of simple maps (difference equations).

See the example files and the figures generated by them in the fig subdirectory.

How to run an example: open the .m example file in MATLAB and change the working directory in MATLAB to this folder.
