%% Surface Plot of Peaks Function % Use the |peaks| function to define |X|, |Y|, and |Z| as 25-by-25 matrices. Then, % create a surface plot. % Copyright 2015 The MathWorks, Inc. [X,Y,Z] = peaks(25); figure surf(X,Y,Z); %% % |surf| creates the surface plot from corresponding values in |X|, |Y|, and % |Z|. If you do not define the color data |C|, then |surf| uses |Z| to determine the color, so color is % proportional to surface height.
