The script should display a 2-dimensional array with n-rows and two columns: The first column should display the years from 0 to n. The second column should display the account balance at the end of each corresponding year.

n = 30;
X = zeros(n+1,2);
X(:,1) = 0:n;
X(:,2) = ...

This is what I have %compute the growth in a savings account

% get_input prompts for and returns the

% three values entered by the user

initial_bal=input('the initial account balance: $');

rate=input('the annual interest rate:');

time=input('the investment duration in years:');

account_balance=initial_bal.*(1+rate).^time

n=10;

X=zeros(n+1,2);

X(:,1)=0:n;

X(:,2)=account_balance;

disp(X);

How do I get the 2nd column to change with the first column?
