Question

USE MATLAB

The lump sum S to be paid when interest on a loan is compounded annually is given by

where is the principal invested, is the interest rate, and is the number of years.

Write a modular program that will plot the amount S as it increases through the years from 1 to n. The main script lumpsum.m will call a function inputyears.m to prompt the user for the number of years (and error-check to make sure that the user enters a positive integer).

The script will then call a function plotlump.m that will plot S for years 1 through n. It shall use 0.05 for the interest rate and Php100,000 for P.

Run your program using:

Number of Years = - 5

Number of Years = 10

Answer 1

PLEASE GIVE IT A THUMBS UP, I SERIOUSLY NEED ONE, IF YOU WANT ANY MODIFICATION LIKE FOR SEPERATE FILE, THEN DO LET ME KNOW

function [ N ] = readNYears
        N = input('Enter a positive integer for n: ');
        while N ~= fix(N) | N < 0
                N = input('Please try again, enter a postive integer for n: ');
        end
end

function plotLumpSum(n)
        int = 0.05;
        P = 10^4;
        Y = 1:n;
        S = P*(1+int).^Y;
        plot(Y,S,'r-*')
        xlabel('Year')
        ylabel('Lump Sum S')
        title('Plot of S for years 1 through n')
end

n = readNYears;
plotLumpSum(n)
