add element to queue in matlab

In MATLAB, there is no built-in data structure for a queue, but it can easily be implemented using MATLAB's basic data structures such as vectors or linked lists.

Here is an implementation of a queue using a simple vector and the built-in end keyword to add an element to the end of the queue, element is added at the end of the vector and dequeue operation can be performed using the pop() method.

main.m
% Initialize an empty queue
queue = [];

% Enqueue elements
queue(end+1) = 3;
queue(end+1) = 5;
queue(end+1) = 7;

% Dequeue elements
queue(1) = []; % remove the first element from the queue

Alternatively, you can implement a queue using a linked list data structure which can be more efficient for large queues. In a linked list, you can use the end or tail pointer to add elements at the end of the queue, and a head pointer to remove elements from the front of the queue.
