looping through 10 frames of 10 slots each

I am trying to loop through a frame numbered from 0 to 9 and each frame has slots numbered 0-9. Multiple loops seems to be error prone here. Any better suggestion?

Arrival_All=zeros(10,10);

for slotted_frame = 0:9 
    slot_index = mod(slotted_frame,slot_num);
    tx_station_id = slot_index;

    for slotted_num_slot = 0:9
        
        if Arrival_All(slotted_frame+1,slot_index+1+slotted_num_slot) <= slot_init && slotted_num_slot==tx_station_id
            disp('arrived packet');
        end
    end
end

WIth your test that slotted_num_slot == tx_station_id then you do not need a loop there: it is simply

if Arrival_All(slotted_frame+1,slot_idx+1+tx_station_id) <= slot_init

yes, good catch. after removing the unneeded variable, code is much better. thanks,
