Were you having some problem translating the wikipedia formula into MATLAB code: http://en.wikipedia.org/wiki/Centroid#Centroid_of_polygon? If so, post your MATLAB code and we'll help. You might split the polygon into triangles and use the law of cosines and law of sines to find the vertex coordinates:
