This update includes the following changes:
- Enable ANP to cope with constant functions
- Make plot's appearance more deterministic
- Replace 'roots' in 'polyratio.m' with 'uvFactor' from toolbox 'NAClab' by Zhonggang Zeng
This version should be able to handle MIMO systems much better because of the better root finding algorithm 'uvFactor'.
The steps that lead to the incorporation of NAClab are documented in #29 and Mathematics StackExchange.
