Dear All,
I have a question about the integration with Python. The equation is as
below:
and I want to get values of I with respect of V. E_F is known. But for
T(E), I don't have explicit equation, but a .dat file containing
two columns, the first is E, and the second is T(E). It is also in the

Sorry for this inconvenience. Since my file is a little large, I think it will
be more difficult for fellows to check. I will now paste the attachment below.
The file for T(E) consists of two columns, the first is E and the second is
T(E). What I want is to integrate this function in a certain

If you do not have a closed form for T(E) you cannot calculate the exact
value of I(V).
Anyway. Assuming T is integrable you can approximate I(V).
1. Way to do:
interpolate T(E) by a polynomial P and integrate P. For this you need
the equation (coefficients and exponents) of P. Integrating is
Hi Enlong
You may try standard numerical integration solutions based on the E and
T(E) columns data provided.

For numerical integration, you should look as numpy and scipy and
perhaps associated packages.

1. There are a lot of spinet codes in many languages for numerical
integration. I may find a good one in Python for you? try SciPy.org (
http://www.scipy.org/about.html) you may find something there.
2. Look at the wiki too: https://wiki.python.org/moin/NumericAndScientific.
I hope this help a
