Jupyter Notebook Fixed Income - Certicificate of Deposit (CD) - Compound Interest Schedule An interest-at-maturity CD earns interest at a compounding frequency, and pays principal plus all earned interest at maturity. Write a function, called CompoundInterestSchedule, that creates and returns a pandas DataFrame, where each row has: time (in years, an integer starting at 1), starting balance, interest earned, and ending balance, for an investment earning compoundedinterest. Use a for(or while) loop to create this table. The equation for theith year's ending balance is given by: Ei =Bi (1+r/f)f where: Ei is year i's ending balance Bi is year i's beginning balance (note: B1 is the amount of the initial investment (principal) r is the annual rate of interest (in decimal, e.g., 5% is .05) f is the number of times the interest rate compounds (times per year) The interest earned for a given year is Ei - Bi Note the term of the investment (in years) is not in the above equation; it is used…

Vector Creation (creating equally spaced vectors) Write a script with commands to create the following vectors and assign to the indicated variable names. ■ Create an evenly-spaced row vector A with elements starting at 0 and ending at 50 with increments of 0.5. ▪ Create a row vector B with 80 evenly-spaced elements starting at 0 and ending at л/2. Your code should not include the following MATLAB functions or keywords: for, while. Hint: one line of your solution should start with A = and the other line of your solution should start with B =

(b) Combine the times vector you created in part (a) with the data from thermocouple to create a matrix containing the times and the thermo- couple data. (c) Recall that the max and min functions can return not only the maximum and minimum values in a column, but also the element number where those values occur. Use this capability to determine the values of times at which the maxima and minima occur in each column. PARTNERE ME
