3. (6 points) Write a MATLAB program (a2q3.m) to define a vector x that takes the values [2 3 4 5] and then uses this vector in mathematical expressions to create and output the following vectors: (a) x1 = [23 32 41 59) (b) x2 = [4 6 8 10 1 14 9 16 25 ] A 2] (c) x3 = [8 6 4 2] Also, compute and output in a single statement the mean of the vectors x1, x2, and x3. 3.
