Translate 3D coordinates on a known surface

Hi. I would like to know if there is a way to translate each 3D coordinate (blue dots) such that they lie on a known red surface.
Below is the code:
Nodes_XFix = load("Nodes_XFix.mat");
Nodes_XFix = Nodes_XFix.Nodes_XFix;
Faces_XFix = load("Faces_XFix.mat");
Faces_XFix = Faces_XFix.Faces_XFix;
coord_XMov = load("coord_XMov.mat");
coord_XMov = coord_XMov.coord_XMov;
figure
plot3(Nodes_XFix(:,1), Nodes_XFix(:,2), Nodes_XFix(:,3),'r.','Markersize',12)
hold on
trimesh(Faces_XFix(:,:),Nodes_XFix(:,1),Nodes_XFix(:,2),Nodes_XFix(:,3),'EdgeColor','r','Linewidth',1,'Facecolor','w')
plot3(coord_XMov(:,1), coord_XMov(:,2), coord_XMov(:,3),'b.','Markersize',12)
hold off
grid off
axis equal
xlabel('x')
ylabel('y')
zlabel('z')
view([15,50,30])

In future, please consolidate your variables into a single .mat file, as I have done here. This reduces the amount of work needed for us to download and import all your variables.

[~,I]=pdist2( Nodes_XFix, coord_XMov,'euc','Smallest',1)
coord_XMov = Nodes_XFix(I,:);
