This tool will use a specified interpolation method to fill in missing values in a matrix. The interpolated values are a function of the neighbouring values.
It is based on Python 3.6. I have put the file in a Python 3 venv, so the Python version is controlled.
- Activate the venv:
source venv/bin/activate - Run the code:
python run.py - Run the tests:
nosetests - Run the tests with coverage:
nosetests --with-coverage --cover-erase --cover-package=interpolation_tool --cover-html
- The core interpolation function has a flaw - the interpolation doesn't work where there are <3 adjacent values i.e. at the corners of the matrix.
- The output of the interpolation function is a .csv file
- The tool can handle adjacent NaNs
- Investigate the 'corner problem', to see if the interpolation can take place for fewer (<3) adjacent values. This is a limitation of the numpy module, and may even be the preferred behaviour.
