One approach:
vertices = randi(9, 10, 2); % Create Vertices Matrix [x(:) y(:)]
verticesc = vertices - mean(vertices,1); % Center Vertices
[~,sortidx] = sortrows(atan2(verticesc(:,2), verticesc(:,1)),1); % Sort
sortidx = [sortidx; sortidx(1)]; % Close Polygon
figure(1)
plot(vertices(sortidx,1), vertices(sortidx,2), '-pr')
axis equal
The ‘vertices’ matrix has the x coordinate in the first column, and the y coordinate in the second column.

I see that this has the tag "3d plots" but you refer to "polygon". If in fact you're referring to the standard definition of polygon as "a plane figure that is bounded by a finite chain of straight line segments closing in a loop" use your coordinates to build a polyshape object and call plot on that polyshape.
