how to map an point of a grid onto the nearest point of that point on another grid

theta=-pi/6:pi/180:pi/6;
phi=-pi/6:pi/180:pi/6;
[theta,phi]=meshgrid(theta,phi);
for rho=5:.025:50
     [x,y,z]=sph2cart(theta,phi,rho);
     xs=min(x(:)):0.03:max(x(:))+1;
     ys=min(y(:)):0.15:max(y(:))+1;
     zs=min(z(:)):0.15:max(z(:))+1;
end

I want to map the any point of (x,y,z) grid onto the nearest point in (xs,ys,zs) grid
