I am trying to create an array that displays the values 1-25 and puts the correct calculation next to it

     bal = input('What is your initial balance '); %%%Takes the user input for intial balance 
    rate = input('What is your annual interest rate '); %%%Takes user input for rate
    A=zeros(25,1); %%%%Creating a 1 by 25 array

    for i = 1:25 %%%%loop for numbers 1-25
    p = ((i/100)/12)*bal; %%%Formula
    r = (rate/100)/12;  %%%Formula
    a = 1 - ((r*bal)/p); %%%Formula
    b= -log(a); %%%Formula
    c = 1 + r; %%%Formula
    d = log(c); %%%%Formula
    n = ceil(b/d); %%%%final calculation    
    A(i)=n; %%%Store values of final calculation

    end
    fprintf('%d\n   %d',i,A); %%%Print out 1:25 and final calculations

You could move the fprintf inside the loop, just before the "end" statement. E.g.,

 fprintf('%2d   %d\n',i,A(i)); %%%Print out i and final calculation for this i

That being said, I think you should double check your code. E.g., this line looks like you are using i as a simple index:

    for i = 1:25 %%%%loop for numbers 1-25

But this line looks like you are using i as an interest rate:

    p = ((i/100)/12)*bal; %%%Formula

It looks rather strange that the interest rate is increasing at each iteration, and I doubt that is what you are intending to calculate.
