nmie-old.cc 3a6320a005 Revised calculation of electric field. Everything seems right now for the calculation outside the particle. Also did several small format changes. преди 10 години
nmie-old.h a098084807 Core calculations ported to C++ class. преди 10 години
nmie-wrapper.cc 553a8d05d1 Reversed changes to scattnlay.pyx because the python extension would compile well but it was not returning the complex vectors (S1 and S2). If changed again we must verify that tes04.py works!!! преди 10 години

How to use scattnlay

Table of contents:

Compile Code:

Compilation options

  • make source - Create source package (python library)
  • make install - Install on local system (python library)
  • make buildrpm - Generate a rpm package (python library)
  • make builddeb - Generate a deb package (python library)
  • make standalone - Create a standalone program
  • make clean - Delete temporal files

Use:

  1. Python library
    • Use scattnlay directly
from scattnlay import scattnlay
...
x = ...
m = ...
terms, Qext, Qsca, Qabs, Qbk, Qpr, g, Albedo, S1, S2 = scattnlay(x, m)
...
  • Execute some of the test scripts (located in the folder 'tests/python') Example:
./test01.py
  1. Standalone program
    • Execute scattnlay directly Usage:
scattnlay -l Layers x1 m1.r m1.i [x2 m2.r m2.i ...] [-c comment]
  • Execute some of the test scripts (located in the folder 'tests/shell') Example:
./test01.sh > test01.csv
  1. C++ library
    try {
      MultiLayerMie multi_layer_mie;
      multi_layer_mie.SetLayersSize(x);
      multi_layer_mie.SetLayersIndex(m);

      multi_layer_mie.RunMieCalculation();

      *Qsca = multi_layer_mie.GetQsca();
      *Qabs = multi_layer_mie.GetQabs();
    } catch(const std::invalid_argument& ia) {
      // Will catch if  multi_layer_mie fails or other errors.
      std::cerr << "Invalid argument: " << ia.what() << std::endl;
      throw std::invalid_argument(ia);
      return -1;
    }
