Final Answer:The function call RemoveLast([11, 21, 53, 95, 21]) will delete the last element of the array printQueue.Explanation:The provided code defines a function RemoveLast that takes an array (printQueue) as an argument and deletes its last element. The function is called with the array [11, 21, 53, 95, 21], resulting in the removal of the last element (21).After the function call, the modified array becomes [11, 21, 53, 95]. The function uses the MATLAB syntax for array manipulation, where the last element of the array is removed using the indexing operation.In summary, the function RemoveLast effectively removes the last element from the given array, and when called with [11, 21, 53, 95, 21], it updates the array to [11, 21, 53, 95]....
