Hi, I don't know how to do event based simulation in matlab. Just need a start for it, this question is a start part of my bigger task.

i have this,

arrival_departure_frequency =
0000    5.9489         0
0000    6.6353         0
0001    6.9292         0
0001    6.9361         0
0001    7.2979         0
0001    7.7989         0
0002    7.9419         0
0002    8.8358         0
0002    8.8383         0
0002    9.0600         0

First column is my event_arrivals and the 2nd column is event_departure. I want to change the value of third column from 0 to 1 when the simulation is in between arrival time and the departure time.

Once the event_departure arrives it again back set to O. Thank you so much.

Hi Aftab, I insist you to use stateflow for this logic. You can create your events and trigger the output based on your logic.

Hello, i have tried up to this point but how can i introduce the departure time with it.

for i =1:10
    timenow = event_arrivals(i);
    no_channels = find(BS_channeltable == 0);
    first_available = min(no_channels);
      if timenow == (event_arrivals(i))&& (first_available ~=0)
          BS_channeltable(first_available)=1;
      end 
      end

Please help me with it.

Hi,

I have managed up to this point but how can i release the channel from it as it will never reach to the departure time of the files.

for i =1:10
  timenow = event_arrivals(i);
  no_channels = find(BS_channeltable == 0);
  first_available = min(no_channels);
    %%Allocating the Channel on the file arrival
    if timenow == (event_arrivals(i))&&(first_available ~=0)         
        BS_channeltable(first_available) = 1;
        fprintf(fid,'Frequency is assigned.\n');

Releasing the channel on file departure

    elseif timenow == event_departures(i)                                     
        release_channel = find(BS_channeltable==1);
           last_occuped = max(release_channel);
            BS_channeltable(last_occuped) = 0;
            fprintf(fid,'Frequency is released.\n');
    end
    end
