This is an example of how to create a triangular plot in MATLAB®.
Read about the triplot function in the MATLAB® documentation.
Go to MATLAB Plot Gallery
% Create a set of points representing a point cloud numpts = 192; t = linspace( -pi, pi, numpts+1 )'; r = 0.1 + 5*sqrt( cos( 6*t ).^2 + (0.7).^2 ); x = r.*cos(t); y = r.*sin(t); % Construct a Delaunay Triangulation of the point set dt = DelaunayTri(x,y); tri = dt(:,:); % Create a triangle plot of the Delauney Triangulation figure; triplot(tri,x,y); axis equal; % Add title and axis labels title('Curve reconstruction from a point cloud'); xlabel('x'); ylabel('y');
