Writing a function that computes the sum from 1 to an input using the while loop?

I need help composing a function that computes the sum of numbers from 1 to n (n being an input) using a “while" loop. I know that this could possibly done without using a loop, but I need to construct one without the loop. The input would be a single integer and the goal that computes the sum from 1 to n.

@Amanda Mnt: the task is rather artificial, so it will not be obvious, nor even a good use of MATLAB. But if your task is to use a while loop then so be it.
To start with: what do you need to loop over? How can you do that? Read about while loops, try some of the examples. Get comfortable with how they work.
Beginners often try to solve everything at once. Relax, you don't need to do that. Split the task into parts, e.g.: what does the loop need to do? How to sum within the loop? Once you understand the parts, then you can put the parts together.

Start with a counter, which runs from 1 to n:
x = 1;
n = 10;
while x < n
disp(x)
x = x + 1;
end
Now inster the code for summing: Add the current value to a variable.
