Welcome to zunzunsite3, a Django site in Python 3 for curve fitting 2D and 3D data that can output source code in several computing languages and run a genetic algorithm for initial parameter estimation. Includes orthogonal distance and relative error regressions. Generates PDF files and surface animations. Based on code from zunzun.com. You will need to install scipy, matplotlib, django, bs4, imagemagick gifsicle and reportlab to run this software. On Debian and Ubuntu, you can run the following: apt-get install python3-scipy python3-matplotlib python3-pil apt-get install python3-django python3-bs4 apt-get install python3-reportlab imagemagick gifsicle then install the pyeq3 fitting code with these commands: apt-get install python3-pip pip3 install pyeq3 You can now cd to the project's top-level directory and run the django development server with the command: python3 manage.py runserver and open the url http://127.0.0.1:8000/ in a browser. Cool! NOTES: the code uses Unix-style process forking, and this is not available on the Windows operating system. My tests show that while both mod_wsgi and gunicorn work fine for Django production servers, the uwsgi process model would not allow os.fork() calls to work as required for this software.
