Please provide the MatLab Code, i can do the rest! Thank you!

For p = 0.5, graph the efficiency of Slotted ALOHA (Np(1 - p)^(N-1)) and Pure ALOHA (Np(1 - p)^2(N-1)) as a function of N, at 30 different (integer) values in [1, 30]. Write a program to do this, do NOT do by hand! It takes about 2 lines to do this in MATLAB. For N = 5, graph the efficiency of Slotted ALOHA and Pure ALOHA as a function of p, at 200 different values in [0.001, 0.999]. Write a program to do this, do NOT do by hand! It takes about 2 lines to do this in MATLAB
