Question

I only need B and C. I don't know how to use fzero or bisection to find the months.

0. Taken from Engineering computations, An introduction using MATLAB and Excel). When an amount of money P in invested at an annual interest rate ofI(expressed as a decimal value, not as a percentage), the total value of the investment A after n years can be computed as follows: We wish to find how many years until the investment reaches a desired amount. Test your code for an initial investment of $10,000, a target value of $100,000 and an interest rate of a. Write MATLAB code to find n to the nearest year using a loop. Prompt the user to enter P, the target amount A, and i. Then, loop until the desired amount is reached.

Explanation / Answer

Part B:

%% Solve System of equation in MATLAB

A=100000;

P=10000;

i=0.1;

f = @(n)A-P*(1+i)^n;

Number_of_years = fzero(f,10)

OUTPUT:

>> solve_sys_eqn

Number_of_years =

24.1589

PART c :

PMT() function in Excel verifies above results.
