C program which finds the minimum of a function using the Neld Mead simplex algorithm
Here's a description of the algorithm: http://en.wikipedia.org/wiki/Nelder–Mead_method
or this link (which I like more than the wiki link) http://www.personal.soton.ac.uk/rchc/Teaching/GTPBootstrap/ExtraDetails/NelderMeadProof.pdf
I've devised a main, header, and associated implementation file. All must be linked for the main to work correctly.
