Storing Output in a Matrix from Multiple Iterations

I am trying to save a certain output (i.e. path) from multiple loop iterations into a matrix. How would this be done?

[dist,path,pred] = graphshortestpath(DG,7,3)

How to store these 'paths' into a matrix for a certain number of iterations?

[Walter Roberson]

paths = cell(number_of_iterations,1);

for K = 1 : number_of_iterations
  [dist, paths{K}, pred] = graphshortestpath(DG,7,3);
end

Notice that I used a cell array here rather than a numeric array. Shortest path operations will typically return different lengths of outputs for different graphs.
