UliEngineering
A Python3 library for: - Data science - Electronics Engineering - Specialized algorithms - Physics which contains a collection of functions I haven't found elsewhere. Some algorithms have also been accepted on my blog https://techoverflow.net/
Pull requests and bugreports of any kind are happily accepted.
Installation
Run this command on your favourite shell:
sudo pip3 install UliEngineeringIn order to install the latest bleeding-edge version, use:
sudo pip3 install git+https://github.com/ulikoehler/UliEngineering.gitWe highly recommend you also install scipy:
sudo pip3 install scipy(you can also use sudo apt install python3-scipy on Debian-based Linux distros).
While scipy is technically optional and listed as an optional dependency, many UliEngineering modules can't be used without it, including (might not be complete!):
- UliEngineering.Length
- UliEngineering.SignalProcessing.Interpolation
- UliEngineering.SignalProcessing.Correlation
- UliEngineering.Physics.JohnsonNyquistNoise
- Some functions in UliEngineering.SignalProcessing.Simulation
- Some functions in UliEngineering.SignalProcessing.Selection
After that you can use UliEngineering from any Python3 instance. Example:
$ python3
Python 3.5.2 (default, Nov 17 2016, 17:05:23)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from UliEngineering.EngineerIO import *
>>> format_value(0.015, "V")
'15.0 mV'

Testing
In order to run the unit tests, first install tox:
pip install --user toxand then just run it in the root directory of the cloned repository
tox
