ketch/RK-opt — pull request #6 by mparsani (2011-12-10 19:14:35+00:00)
Title: Multistart

This pull request add the capability to run the rk_opt function using the MATALB multistart solver (Global Optimization Toolbox) both in serial and in parallel.
This pull request deliveries also:

- capability to write the coefficients of the optimized RK methods to a file
- test of the order of accuracy of the method up to 6th-order (credits goes to Yiannis)
- regression test of the new implementation using 40 starting points.

The next step is to write a script that call this function and optimize several RK methods from multi-stability functions.
