Insert multiple vector into single data.

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 =
Columns 1 through 7
39.293765408776999  37.696153649941529  26.925824035672520  47.169905660283021  47.169905660283021  25.495097567963924  43.011626335213137

Columns 8 through 10
47.423622805517503  39.000000000000000  43.011626335213137

baseStation.x = 50;
baseStation.y = 50;
numNodes = 100;

Hope someone can suggest/advice me how to solve this.

Thanks.

Where is the data file/s??

YOur node is a structure. The error clearly shows that node doesn't have the field dist.
