Projection documentation

Welcome to documentation for Projection!

Projection provides a small function that computes the stereographic projection of a point cloud in $R^N$ to a point cloud in $R^{(}N-1)$:

$$P(x,y,z,...,t)\Rightarrow P(x^{\prime },y^{\prime },z^{\prime },...)\text{ where }{x}^{\prime }=x/(1-t),y^{\prime }=y/(1-t),z^{\prime }=z/(1-t),...$$

Example:

from projection import stereographic_projection
import numpy as np

print(stereographic_projection(np.random.rand(1,4)))
# array([[ 0.14022471,  0.96360618,  0.94909878]])
