I have the followig formula
W = N!/h!(N-h)! how do I write a loop when 30, and h =30
for h=1:30
W(h)= factorial(30)/factorial(30)*factorial((30-h))
end
This is what I have so far

I see one other problem in the code you have written.
I would guess that really, the formula you WANTED to write is:
W(h) = N! / (h! * (N-h)!)
where both of these terms are in the denominator. Since that formula is pretty classic, I'm willing to bet this is true.
So what is the problem? Look at the expresion:
A/B*C
For example, what is 9/3*3 in MATLAB? Should it be 1? Or how about 9? Any guesses? It is 9.
9/3*3
ans =
9
So really, what you wanted to write is this:
W(h) = factorial(30)/(factorial(h)*factorial(30-h));
Or, you could have written it as
W(h) = factorial(30)/factorial(h)/factorial(30-h);
Either will work. Well, I'm willing to bet it is something like that.
