question regarding reading .dat file in matlab

Hi,

I've a dat file that looks like this:

   17    9    0.010426
   18    6    0.024578
   19    8    0.018038
   19   17    0.032405

I was wondering how I could read it in matlab. I have written the following code, but it doesnt give me the right answer. Is there a different way to read .dat file in matlab. I am new to matlab so please help.

function [costs] = adjacencyMatrix(filename)
filename = 'alnet3.dat';
      delimiterIn = ' ';
      startRow    = 1;
      startCol    = 1;
      M           = dlmread(filename,delimiterIn,startRow,startCol);
      N    = M(1,1); 
      node1       = M(3:end,1);
      node2       = M(3:end,2);
      cost        = M(3:end,3);
       pairs = sparse( node1, node2, cost ,N, N ) ;
       pairs = pairs + pairs.';
 costs = full(pairs);

end

If the file is like the one you have posted, you can use the load command
