Problem within the while loop

Hi everyone, This code is running but the problem which i have is in the statement enclosed in the ********. Every time the while loop executes it should remove the first value from the arrival variable but it is not doing what it should do, like removing the first value one by one during each loop iteration.

 tmax = 30;
  nowtime = 0;
  A = 2;
  D = 2;

while nowtime < tmax
nowtime = min(arrivals);
available_channels = find((BS_channeltable)==0);
first_available = min(available_channels);
BS_channeltable(first_available) = 1;           % Allocating the channel to busy status (1)
fprintf(fid,'\n One channel is allocated.');
* * * * * *arrivals = arrivals(A:end);* * * * * *

A = A+1;

if nowtime >= min(departures);
    occupied_channels = find((BS_channeltable)==1);
    first_release = min(occupied_channels);
    BS_channeltable(first_release) = 0;         % Allocating the channel to idle status (0)
    fprintf(fid,'\n One channel is released.');
    departures = departures(D:end);
    D = D+1;

elseif nowtime > max(departures)
    fprintf(fid,'\nNo more events to arrrive or depart, simulation stops.');
    return;
end
end

Is arrivals a (1 x XXXXX) or (XXXXXX x 1) array?

its a (XXXXXX x 1) array.

Is this what you want to do?

Example:

arrivals = 1:10;
A = 1;
for k1 = 1:5
    arrivals = arrivals(A:end)
    A = 2;
end
