    %% 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 plot's resolution.
