Problem 2

Because I use Matlab, I want the right answer for Matlab program.

You are to write a function called setplay which receives an arbitrary number of numeric vectors and has the following three properties: Note: You may NOT use the MATLAB built-in functions intersect, union, unique, setdiff. Note: You should use varargin/varargout for input/output. i) When a single output is expected at call, the function returns a single vector obtained as the concatenation of the individual input vectors passed to the function, e.g.: >> setplay([11, 8], [5, 1, 8, 2]) ans = 11 8 5 1 8 2 >> a = setplay([2, 5, 1], [9, 3, 7, 1], [3, 5]) a = 2 5 1 9 3 7 1 3 5 When a second (optional) output is expected at call, the function returns for the first output the same as in case (i), while for the second output it returns the same elements as in the first output vector but with no repetitions, e.g.: >> [a, b] = setplay([11, 8], [5, 1, 8, 2]) a = 11 8 5 1 8 2 b = 11 5 1 8 2 >> [a, b] = setplay([2, 5, 1], [9, 3, 7, 1], [3, 5]) a = 2 5 1 9 3 7 1 3 5 b = 2 9 7 1 3 5 When and a third (optional) output is expected at call, as in [a b c] = setplay(vec1, vec2, ...), the function returns for the first and second output the same as in case (ii), while for the third output it returns vector of indices such that a(c) = b. For example: >> [a, b, c) = setplay([11, 8], [5, 1, 8, 2]) a = 11 8 5 1 8 2 b = 11 5 1 8 2 C= 1 3 4 5 6 >> [a, b, c) = setplay([2, 5, 11, 19, 3, 7, 11, [3,5]) a = 2 5 1 9 3 7 1 3 5 b = 2 9 7 1 3 5 1 4 6 7 8 9 Code to call your function 1 a = setplay([2, 5, 1], [9, 3, 7, 1], [3, 5]) 2 [a, b] = setplay([11, 8], [5, 1, 8, 2]) 3 [a, b] = setplay([2, 5, 1], [9, 3, 7, 1], [3, 5]) 4 [a, b, c] setplay([11, 8], [5, 1, 8, 2]) 5 [a, b, c] = setplay([2, 5, 1], [9, 3, 7, 1], [3, 5]) =
