return value did not change

hye, here is my code, other variable is working except for r(i+1),it return the same value for i=0 until 100 ,can someone tell me how to solve this?

function [Resistant ] = resistance(w,l,h)
G = 1.59*10.^-8;
u =pi*4*10.^-7;
p= 6.30 *10.^7;
f = 0:100;
for i= 0:100;
    q(i+1)=(2/(2*pi*f(i+1)*u*G)).^(1/2);
    v(i+1) =1-exp(-h/q(i+1));
    r(i+1)= w*q(i+1)*v(i+1)
    Resistant(i+1) = p*l/r(i+1);
end
end

@rose wright: please give us the exact values of w, l, and h that you used.

here is the value

resistance(5*10.^-5,0.248,5*10.^-5)

If you are so certain r(i+1) is the same for every i I assume you are using the debugger so surely it is easy to see what the problem is if you are? Just look at its components on the command line each time round the loop.

If it isn't changing it suggests that q * v is constant for each iteration.
