% The Ramer–Douglas–Peucker algorithm (RDP) is an algorithm for reducing
% the number of points in a curve that is approximated by a series of
% points. The initial form of the algorithm was independently suggested
% in 1972 by Urs Ramer and 1973 by David Douglas and Thomas Peucker and
% several others in the following decade. This algorithm is also known
% under the names Douglas–Peucker algorithm, iterative end-point fit
% algorithm and split-and-merge algorithm. [Source Wikipedia]
%
% Input:
% Points: List of Points 2xN
% epsilon: distance dimension, specifies the similarity between
% the original curve and the approximated (smaller the epsilon,
% the curves more similar)
% Output:
% result: List of Points for the approximated curve 2xM (M<=N)
