draw a landscape in matlab

To draw a landscape in MATLAB, we can begin by generating an elevation map using the peaks or fspecial function, and then plot it as a 3D surface.

Here's the code to generate a landscape using the peaks function:

main.m
[X,Y] = meshgrid(-3:0.1:3);
Z = peaks(X,Y);
surf(X,Y,Z)

And here's the code to generate a landscape using the fspecial function:

main.m
h = fspecial('gaussian',[100,100],20);
H = 10*pascal(100); % set an elevation scaling factor
Z = H.*imfilter(randn(100,100),h);
surf(Z);

These are just two examples of how you can generate an elevation map for a landscape in MATLAB. Once you have an elevation map, you can customize the plot further by adding a colormap, adjusting the viewing angle, and adding lighting.
