make a color coded 3d surface plot in matlab

To make a color coded 3D surface plot in MATLAB, we need to first generate the data for the surface and then use the ‘surf’ function to plot the surface with color mapping. Here is an example code to create a color coded 3D surface plot:

main.m
% Generate some data for the surface
[X, Y] = meshgrid(-10:0.1:10);
Z = sin(sqrt(X.^2 + Y.^2))./sqrt(X.^2 + Y.^2);

% Create a color map using the Z values
C = Z;

% Plot the surface with color mapping
h = surf(X, Y, Z, C);
set(h, 'EdgeColor', 'none');
colormap(jet);
colorbar;

In this code, we use the meshgrid function to create X and Y matrices for the surface, and then calculate the Z values using the sine function. We then use the ‘surf’ function to plot the surface with the Z values used for the color mapping. The ‘set’ function is used to remove the edges of the surface, and the ‘colormap’ and ‘colorbar’ functions are used to add color to the surface.
