Why do you ask the same question again ?
It has been answered here:
But you can also call it directly from MATLAB using
s = expint(x,2)
And the definition of E_n is here under the point "Generalization":

I think that's idiotic.
People who work with expint want it to have numerical output with numerical input, I guess.
