NSphere¶ ↑

A ruby implementation of n-sphere.

In two dimension, it is a circle, and in three dimension it is a sphere. For high dimensions, the n-sphere is like a high dimension vectors, which has a distance of certain length to a point. See the above wikipedia page for detailed explanation.

Install¶ ↑

gem install nsphere
