%% 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.

subplot(2,1,2)
fcontour(sin(x).*sin(y),'MeshDensity',200)
title('Increased MeshDensity = 200')
