Hi, i have some problem here, how can i add multiple data into "node(i).dist ". Here is the code.

for i = 1:1:numNodes
if node(i).tier == 1
   node(i).dist = sqrt((node(i).x - baseStation.x).^2 + (node(i).y - baseStation.y).^2);
   dist_tier1(i,1) = node(i).dist;
end
  end

It contain error:

>> node(i).dist
Reference to non-existent field 'dist'.

The details:

sqrt((node(i).x - baseStation.x).^2 + (node(i).y - baseStation.y).^2)
ans =
