This function uses a dumb search to find the minimum distance between a point (or many points) and an ellipse. It has controllable accuracy which may be reduced for faster computation.

*Update 12 Jan 2010: Rody Oldenhuis has submitted a version of this file (possibly only for versions >=Matlab 2009a) that works for general 3D ellipses and should be more efficient than this one. Please see acknowledgements below.

*Update 08 Jan 2010: fixed a bug in original file
