%% Query Data Aspect Ratio % Create a surface plot and query. % Copyright 2015 The MathWorks, Inc. [x,y] = meshgrid(-2:.2:2); z = x.*exp(-x.^2 - y.^2); surf(x,y,z) %% % Query the data aspect ratio. The ratio indicates that the length of four % units in the _x_-axis direction equals four units in the _y_-axis % direction and one unit in the _z_-axis direction. For example, the length % from 0 to 1 on the _x_-axis equals the length from 0 to 1 on the _y_-axis % and 0 to 0.25 on the _z_-axis. d = daspect
