hi ,need some help in tensor case. i want to chain 3d meshgrid in once and create "image tensor" due to the movement meshgrid

 s = -10:10;
 t = -10:10;
 [S,T] = meshgrid(t,s);
 
 L = cat(3,S,S+1,S+2,T,T+1,T+2);
 
 r1 = rand(50,50);
 r2 = rand(50,50);
 rc = single(complex(r1,r2));
 
 L = int32(L);
 
 R = rc(L);

I don't understand the question. Can you show the result yo uwna to achieve?

R suppose to be 50*50*6
