How to calculate the average value of energy samples obtained from simulation

At the end of simulation a vector of size tmax (residual_energy) is generated: it contains all the values of residual energy at t varies from 1 to tmax. This is the vector I'd like to plot. I would like to carry out the simulation 20 times and then use the average of the results. This is the solution I thought:

      %create the energy matrix (sim_number X tmax): each row represents the residual_energy vector

      for trial = 1:sim_number

          run simulation;

          energy(trial,:) = residual_energy;

      end

      %I get the final vector by averaging column by column

      for t = 1:tmax

          average_residual_energy = mean(energy(:,t));

      end

      plot(average_residual_energy);

Is this method to obtain the average value correct? Please help, this is my first simulation!

You do not need a for loop

   average_residual_energy = mean(energy)

Ok, i don't need a loop. But I want to know if the method is right! I mean, the average value of energy at time t1 is the average of all values of energy at t1 in every simulation?
