What command to move from random node location to specific node location

I want to solve a problem about node placement. Now I want to know how to move node from random placement to specific placement. I need command to move the node. I already create for random node but I don't know how to move the node from random to specific location.

Hi liza, firstly i am sorry for my english ; i am working on optimal node placement problem , i don't know how your problem is modeled, so i will try to give you an example if you have a matrix binary matrix b : b=1 if node is placed in position (i,j) ( matrix indices):

if true
  %%Creating the dimensions of the room
x = linspace(0,24,9);
y= linspace(0,24,9);
% Number of Beacon (nodes)
N=25;
% fixe  ramdomly  the beacon 
b = zeros(9,9);
b(randperm(numel(b), N)) = 1;

if true
  %find the coordinate (positions) of the nodes   X,Y
[m,n]=find(b==1);
m=m';
n=n';
%
for i=1:length(m)
  for j=1:length(n)
  B(i,:)=[x(m(i)) y(n(i))] ; %disply coordinate of node (metter)  
   end 
end
end
end

you can move her beacon horizontally or diagonally or in specific position (index) ; example:

if true
   % right horizontal
   c= b((m(i)),n((i)+1))
   b((m(i)),n((i)+1))=b(m(i),n(i)) % horizontale droit
   b(m(i),n(i))=c
   movH=b
end
%left horizontal 
c=b((m(i)),n((i)-1))
b((m(i)),n((i)-1))=b(m(i),n(i)) % horizontale Gauche
b(m(i),n(i))=c
movH=b;
% m and n are vectors containing the indices of the beacons. i = 2 selects the second elements of vector m and n which gives the position (index) of the beacon N°: 2.
i = 3 beacon N° 3 
end
