@salim saeed,

To plot a figure you have shared, you would need the function that is plotted. There is an inset plot in the figure too.

You can follow these steps -

• Collect the x,y,z points
• Use the surf function to create the 3D plot
• Set colormap
• Use "hold on" to add inset plot in the same figure
• Add labels for the plot
• Create inset plot
• Set axis limit and aspect ratio

Suppose you want to plot ,

% Define x,y,z points
[x, y] = meshgrid(linspace(-20, 20, 100), linspace(-20, 20, 100));
z = sin(sqrt(x.^2 + y.^2)) ./ sqrt(x.^2 + y.^2);

% Create the 3D surface plot
figure;
surf(x, y, z, 'EdgeColor', 'none');
colormap(jet);
hold on;

% Add a plane
planeZ = zeros(size(x));
surf(x, y, planeZ, 'FaceColor', 'yellow', 'EdgeColor', 'none', 'FaceAlpha', 0.5);

% Set labels
xlabel('x');
ylabel('y');
zlabel('u(x,y)');

% Create inset plot
axes('Position', [0.7, 0.7, 0.2, 0.2]);
plot(x(1, :), z(50, :), 'k', 'LineWidth', 1.5);
xlabel('x');
ylabel('u(x)');
title('Inset');

% Adjust view
view(3);
axis tight;
