2a We are given the function f (x, y) = x2 + y2 + xy. Write an inline function that accepts vectors of x and y to generate the value of the function. Output the answer for x = -2:2 and y = -1:3. 2b Use a scatter plot scatter3(argi, arg2, arg3) to visualize your answer now using x=-2:0.1:2 and y=-2:0.1:2. 2c Plot this function (2D surface) between x = (-2,2) and y = (-2,2) using the scatter3() function. You will need to generate all permutation of (x,y) points as follows: K = [1 2]; y = [2 3]; xp = [1 2 1 2]; yp = [2 2 3 3]
