%% Control Resolution of Contour Lines % Control the resolution of contour lines by using the |'MeshDensity'| % option. Increasing |'MeshDensity'| can make smoother, more accurate % plots, while decreasing it can increase plotting speed. % % Divide a figure into two using |subplot|. In the first subplot, plot the % contours of $\sin(x)\sin(y)$. The corners of the squares do not meet. To % fix this issue, increase |'MeshDensity'| to |200| in the second subplot. % The corners now meet, showing that by increasing |'MeshDensity'| you % increase the resolution. f = @(x,y) sin(x).*sin(y); subplot(2,1,1) fcontour(f) title('Default Mesh Density (71)') subplot(2,1,2) fcontour(f,'MeshDensity',200) title('Custom Mesh Density (200)')
