3. (4 points) Write a MATLAB program (a2q3.m) to define a vector v that takes the values [3 4 5 6 7] and then uses this vector in mathematical expressions to create and output the vectors v1, v2, and v3 as follows: = (a) v1 [22 31 40 5-162] (b) v2 = 8 10 12 14 -[1,10 10 10 78 9 (c) v3 [-2-3-4-5-6] Also, compute and output in a single statement the sum of all the values in the vectors v1, v2, and v3.
