Question

1. Write a matlab program that takes a number from the user as an input and outputs whether the number is
perfect or not.
Example run:
Input number: 5
Not a perfect number!
Input number: 28
Perfect number!

2. Write a matlab program to generate a list of perfect numbers!. (at least up to 6)
Example run:
How many perfect numbers do you wish for? 4
6 28 496 8128

I feel as if I am overthinking this problem. If someone can help me out and explain how to solve this it will be greatly appreciated.

If you don't know a perfect number is a number whose divisors all add up to equal that number.

For example: 6

6 can be divided by 1, 2, and 3.

1+2+3=6

6 is a perfect number.

The number 8 is not a perfect number because 1,2, and 4 do not add up to 8.

Thanks you guys

Explanation / Answer

% 1. Write a matlab program that takes a number from the user as an input and outputs whether the number is
% perfect or not.
k = input('Input number: ');
sum = 0;
for i=1:k-1
   if mod(k,i)==0
   sum = sum + i;
   end
end
if sum != k
fprintf(' Not a perfect number!')
else
fprintf(' Perfect number!')
end

% 2. Write a matlab program to generate a list of perfect numbers!. (at least up to 6)
k = input('How many perfect numbers do you wish for? ');
count = 0;
p = 2;
fprintf(' ');
while count < k
sum = 0;
   for i=1:p-1
       if mod(p,i)==0
       sum = sum + i;
       end
   end
   if sum == p
   fprintf('%d ',p);
   count++;
   end
p++;
end
