Generate random vectors whose components sum up to one

This Python3 module implements different approaches [1] to randomly and uniformly generate d-dimensional vectors whose components sum up to one.

Installation

Run the following to install the module:

pip install pyrandvec

Usage

from pyrandvec import sample

# Generate 10 4-dimensional vectors with the simplex-method
sample(10, 4, method = 'simplex')

# Generate 10 3-dimensional vectors with the trigonometric methdod with subsequent shuffling
sample(10, 3, method = 'trigonometric', shuffle = True)

Developing randvec

To install the pyrandvec module along with the tools you need to develop and run test, run the following command in your virtual environment (virtualenv):

pip install -e .[dev]
