4. Tribonacci Series The Tribonacci series is an extension of Fibonacci series. The tribonacci numbers are defined as the sum of three preceding ones, with: For n = 1, 2, 3: T(1) = T(2) = 0, T(3) = 1 For n>3: T(n) =T(m - 1)+T(x 2) +T( 3) Write a recursive function that returns the Tribonacci sequence: 1 function T = tribarray (n) for n>3. Hints: (a) Your output, T, should start with the value of T(1) even though it is not part of the recursion. For example, calling tribarray(7) returns [0 0 1 1 2 4 7]. (b) Use nested functions; consult this week's Discussion
