how to make a fifo queue in matlab

To make a FIFO queue in Matlab, you can use the built-in queue data structure. Here's an example of how you can create and use a FIFO queue:

main.m
% create a queue object
q = queue;

% add elements to the queue
enqueue(q, 'apple');
enqueue(q, 'banana');
enqueue(q, 'cherry');

% get the first element in the queue
elem = dequeue(q);

% iterate through the queue
while ~isempty(q)
    elem = dequeue(q);
    disp(elem)
end

In this example, we create a queue object using the queue function. We then add elements to the queue using the enqueue function. The elements are added to the back of the queue, so the order is preserved.

To get the first element in the queue, we use the dequeue function. This removes the element from the front of the queue and returns it.

Finally, we iterate through the remaining elements in the queue using a while loop and the dequeue function.

Note that queue is part of the DataQueue class, which is a handle class. This means that modifying the queue object will affect all references to it.
