Library implementing conformal geometric algebra.
The key features are:
- Fast numerical implementation of multivector and its exterior algebra
- The library supports various backends (numpy, tensorflow, jax)
- Full support of autograd works when using jax and tensorflow
- All operation work for single multivector or tensors of multivector. Broadcasting is also supported.
