(a) Write a function to generate n random integers between -b and b. (b) Using the function you wrote in (a) generate 50 random numbers in a vector A where b = 100; (e) This array A will contain both negative, positive and possibly zero entries. Write a MATLAB script to compute the percentage of positive, negative and zero entries in the array. (d) Show all necessary data; For example let's say your array is A = [-2,-1,0, 1,2]. The percentage of positive, negative and zero entries is 40%, 40% and 20%
