How I can plot surface countour plot and velocity plot on same garph using MATLAB

Hi Sharad,

This can be achieved by using the "hold" feature of MATLAB. The below code demonstrates how to do the same:

% Generate example data for the surface
[X, Y] = meshgrid(-2:0.1:2, -2:0.1:2);
Z = X .* exp(-X.^2 - Y.^2);

% Generate example data for the velocity field
[U, V] = gradient(Z);

% Create the contour plot
figure;
contourf(X, Y, Z, 20); % 20 specifies the number of contour levels
colormap(jet); % Select a colormap
colorbar; % Display the colorbar
hold on; % Retain current plots to add more

% Overlay the velocity field
quiver(X, Y, U, V, 'k'); % 'k' denotes black arrows

% Add labels and a title
xlabel('X-axis');
ylabel('Y-axis');
title('Surface Contour Plot with Velocity Field');

% Adjust axis limits if necessary
axis tight;
hold off;

For more details, please refer to the following MathWorks documentation: https://www.mathworks.com/help/matlab/ref/hold.html

Hope this helps!
