    %% Display Image Along Surface Plot
% Use the |peaks| function to define |XD|, |YD|, and |ZD| as 25-by-25 matrices.

% Copyright 2015 The MathWorks, Inc.


[XD,YD,ZD] = peaks(25);

%%
% Load the |clown| data set to get the image data |X| and its associated colormap,
% |map|. Flip |X| using the |flipud| function and define
% the flipped image as the color data for the surface, |C|.
load clown
C = flipud(X);

%%
% Create a surface plot and display the image along the
% surface. Since the surface data |ZD| and the color data |C| have different dimensions, you must set the
% surface |FaceColor| to |'texturemap'|. 
figure
surface(XD,YD,ZD,C,...
    'FaceColor','texturemap',...
    'EdgeColor','none',...
    'CDataMapping','direct')
colormap(map)

%%
% The clown data is typically viewed with the |image| function, which
% uses |'ij'| axis numbering. This example reverses the image data in the
% vertical direction using |flipud|.
