Why does my loop only run once

function I=trapezoidal(f,a,b,n)

h=(b-a)/n; % length of the interval

total=0;

x=a;

fa=f;

x=b;

fb=f;

for i=n

x=i;

fn=f+total

total=fn

end

I=fa+fb+2*fn;

end

I assume that your parameter n is a scalar? If you want to let your script loop from 1 through n, you use for i = 1:n.

Okay, thank you very much!
