You learn to use vectors? You learn to use loops? Really, you need to learn MATLAB.

I think that what you're asking about is using the input function to gather multiple values, and then passing those values into the sum function. If I'm incorrect, maybe you could give a little more detail in your question
You can accept a vector from 'input' using square brackets:
>> x=input('Enter some numbers, use brackets to specify a vector: ');
Enter some numbers, use brackets to specify a vector: [1 1 2 3 5 8]
>> sum(x)
ans =
20
An alternative design might be to use a loop, keep prompting for more numbers:
Script
x = 0;
next = 0;
prompt = "Enter a number, or hit enter without any value to compute sum: ";
while(~isempty(next))
next = input(prompt);
x=[x next];
end
sum(x)
Run
Enter a number, or hit enter without any value to compute sum: 1
Enter a number, or hit enter without any value to compute sum: 1
Enter a number, or hit enter without any value to compute sum: 2
Enter a number, or hit enter without any value to compute sum: 3
Enter a number, or hit enter without any value to compute sum: 5
Enter a number, or hit enter without any value to compute sum: 8
Enter a number, or hit enter without any value to compute sum:
ans =
20
