how to remove repeated data in an array in matlab

main.m
        Here is an example:

        ```matlab
        % create an array with repeated values
        A = [1 2 3 3 4 5 5 5];
        % use unique() function to remove repeated values
        B = unique(A)
        ```

        The output of the code above would be:
        ```
        B =
            1 2 3 4 5
        ```
        As you can see, the unique() function has removed any repeated values from the original array A, and returned the unique values in array B.
