Please help me write, the functions in mattlab. I am confused thank you.

1) computeRing Area a Write a function named computeRingArea that takes in the radii, a and b, of the inner and outer rings respectively, and returns the area of the ring (which is shaded in the figure below). 2) Odds and Evens ODD EVEN Write a function named numOddsAndEvens that takes in a vector of integers, x, and returns two values, num Odds and numEvens. numOdds is the number of odd-valued elements in x, and numEvens is the number of even-valued elements in x. 3) FizzBuzz 12.4.78 - 12Z 131114 Fizz Bu 16 Write a function named fizzBuzz that takes in an integer n. For each value in the range 1 to n, the program displays one of three words: fizz (if the number is divisible by 3), buzz (if the number is divisible by 5), or just the number (e.g. 1, 2, 4). The function does not return any value. 1) computeRing Area a Write a function named computeRingArea that takes in the radii, a and b, of the inner and outer rings respectively, and returns the area of the ring (which is shaded in the figure below). 2) Odds and Evens ODD EVEN Write a function named numOddsAndEvens that takes in a vector of integers, x, and returns two values, num Odds and numEvens. numOdds is the number of odd-valued elements in x, and numEvens is the number of even-valued elements in x. 3) FizzBuzz 12.4.78 - 12Z 131114 Fizz Bu 16 Write a function named fizzBuzz that takes in an integer n.
