How to integrate (e^x)/x from limit 1 to 2 using inbuilt commands?

How to integrate (e^x)/x from limit 1 to 2 using inbuilt commands? i tried doing this by defining a function f using inline and then trying to solve the integration by using quad(f,1,2) An error occurred saying "The integrand function must return an output vector of the same length as the input vector. " please help asap.

Basically, Riemann Sum Implementation should help you here:

f=@(x) exp(x)./x;
dt=0.0001;
ii=1:dt:2;
res=0;
for k=1:numel(ii)
    res=res+f(ii(k))*dt;
end
res

The res value is the same with

 result=integral(f,1,2)

Hope this helps.
