2. Write a function "GenMatrix" that takes two inputs of m and n as numbers of rows and columns, and create a matrix for which each element is equal to ij ( i is row and j is column) using two "for loops". If m=3,n=4, for example, the following matrix will be created: A=1232463694812 3. If your savings account is giving you r=1% interest per year, and interest is added to your account on a monthly basis, as: A=p(1+12r)M in which p=10000 is the amount you put into your account, M is number of months, and A is your accumulated savings (with interests). a. Write a "for loop" that calculates your savings amount at the end of each month, for 120 months. Plot your savings versus months. b. Using a "while loop", how many months does it take for your savings to reach 20000 dollars? Will you be alive to enjoy that amount
