How can I display the result in table for an user defined functions?

An amount of money P is invested in an account where interest is compounded at the end of the period. The future worth F yielded at an interest rate i after n periods may be determined from the following formula: F = P(1 + i)n

Write a script to calculate the future worth of an investment for each year from 1 through n. The input from the user should include the initial investment P, the interest rate i (as a decimal), and the number of years n for which the future worth is to be calculated. The output should consist of a table with headings and columns for n and F. Use the fprintf command to achieve a clean and readable format for the table. The following is the expected output from the program for P = $100, 000, i = 0.05 (that is, a 5% interest rate), and n = 10 years.

    Enter initial investment in dollars: 100000
    Enter the interest rate: 0.05
    Enter number of years: 10
    year future worth
    0 100000.00
    1 105000.00
    2 110250.00
    3 115762.50
    4 121550.63
    5 127628.16
    6 134009.56
    7 140710.04
    8 147745.54
    9 155132.82
    10 162889.46

function furtureworth P=input('Enter initial incestment (dollars):'); i=input('Enter the interest rate (decimal):'); n=input('Enter the number of years:');

x = 0:n;

if (i>=0) F=P*(1+i).^x; y = [x;F]; end

if(i<0)||(P<0) fprintf('sorry,the value of i is not valid for calculation \n'); end

fprintf('\n year future worth\n'); fprintf('%5d %14.2f\n',y)

Hint: for "The input from the user" use the input() function. Then use a for loop , and put the future worth in there and also the fprintf

for y = 1 : numberOfYears
  futureWorth = .......some equation............
  fprintf('%d %.2f\n',......................
end

I hope that's not giving too much away.
