function Visualize2(X, Y, E, F, k)
 
    if k==4
        k1=2; k2=2;
    elseif k==2
        k1=1; k2=2;
    end
    figure;
    
    X=X'; Y=Y'; E=E'; F=F';
    
    
    %Show the original manifolds
    subplot(k1,k2,1);
    plot3(X(:,1), X(:,2), X(:,3),'r-', 'LineWidth',.5);
    hold on;
    plot3(Y(:,1), Y(:,2), Y(:,3),'b-', 'LineWidth',.5);
    title({['(A) Before Alignment']});
    xlabel('X', 'FontSize',12, 'FontWeight', 'bold');
    ylabel('Y', 'FontSize',12, 'FontWeight', 'bold');
    zlabel('Z', 'FontSize',12, 'FontWeight', 'bold');
  
    % 3D
    subplot(k1,k2,4);
    plot3(E(:,1), E(:,2), E(:,3),'r-', 'LineWidth',.5);
    hold on;
    plot3(F(:,1), F(:,2), F(:,3),'b-', 'LineWidth',.5);
    title({['(B) After 3D Alignment']});
    xlabel('X', 'FontSize',12, 'FontWeight', 'bold');
    ylabel('Y', 'FontSize',12, 'FontWeight', 'bold');
    zlabel('Z', 'FontSize',12, 'FontWeight', 'bold');
    
    if k==4

在 MATLAB Online 中打开

mesh(xq1, xq2, xq3, 'r');

and

mesh(yq1, yq2, yq3, 'b');

and

title('(A) Before Alignment')

Zain Khaliq 2020-1-19

the title thing worked, however for color i get the follwoing error :

Error using mesh (line 63)

Property value pairs expected.

Error in Visualize1 (line 69)

mesh(xq1, xq2, xq3,'g');

Error in cmp2All (line 39)

Visualize1(X1, X2, map1(:,1:3)'*X1, map2(:,1:3)'*X2, 4);

Use surf()

surf(X(:,1), X(:,2), X(:,3), 'EdgeColor', 'none');

If that doesn't work, attach your X, Y, E, F, and k in a .mat file with the paper clip icon.

were you able to see the code? from the link I provided above ? the problem is my professor doesnt like the lines in that graph, beacuse when I replace the authors data with mine and run the code, my data looks like its noise signal, eventho its not so my professor said if you can represent these as surface plot it would look much smoother.

Sorry but I'm not going to be able to have the time to donate to you to delve into this. Basically you need to figure out how to use surf() if you want a surface plot. It should not be hard or beyond your capabilities - you're a smart scientist so I'm sure you can do it.
