Extracting the value from Netcdf file with longitude and lattitude

Hi, My question may be confusing. Now I would like to extract temperature values from model output with python. My model output have separate temperature, longitude and latitude variables. So, I overlap these three grid variables on one figure to show temperature with longitude and latitude thr

The possibility integration in Python without an equation, just an array-like file

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 at

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 r

Re: The possibility integration in Python without an equation, just an array-like file

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

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 bi

Loading modules from files through C++

I'm using Python in an embedded situation. In particular I have to load python scripts through a memory interface so regular python module loading can not be used. I got working so far a module loader object I've added using C++ to sys.meta_path . Now I'm totally stuck at the finally loading step.
