MATLAB: Sum of integers up to n using a while loop

sumwhile loop

Hi, I've recently started coding as part of my uni maths course, however I am struggling very much with the learning curve.

I want to know how to sum all the positive numbers up to and including n by using a while loop.

From what I have gathered already I would use in the case of n = 10

s = 0
n = 10 
while s < ((n + 1) * n / 2)
    N = N + 1
    s = s + N
end
disp(s)

What could I do to make this work? Any help would be greatly appreciated,

try it yourself with a for (see documentation)

You can be guided by this example:

s = 0;
k=1;
n = 10 ;
while k <= n
    s=s+k;
    k=k+1;
end
disp(s)

In the end, the idea is that with practice you can do all this code in a line like this:

n=10
s=sum(1:n)

kk = 10;
k = 1;
f = 1;
while k <= kk
    f = k * f;
    k = k + 1;
end
format long
disp(f)

 n{1} = '0' ;
 n{2} = '01';
 k=3;
    while k<=13
        n{k} = horzcat(n{k-1},n{k-2});
        k=k+1;
    end
    n{end}
