lgatr.interface.pseudoscalar

Embedding and extracting pseudoscalars into multivectors.

Functions

`embed_pseudoscalar`(pseudoscalars)	Embeds a pseudoscalar tensor into multivectors.
`extract_pseudoscalar`(multivectors)	Extracts pseudoscalar components from multivectors.

lgatr.interface.pseudoscalar.embed_pseudoscalar(pseudoscalars)[source]

Embeds a pseudoscalar tensor into multivectors.

Parameters:: pseudoscalars (torch.Tensor) – Scalar inputs with shape (…, 1).
Returns:: multivectors – Multivector outputs with shape (…, 16). multivectors[..., [15]] is the same as pseudoscalars. The other components are zero.
Return type:: torch.Tensor

lgatr.interface.pseudoscalar.extract_pseudoscalar(multivectors)[source]

Extracts pseudoscalar components from multivectors.

Parameters:: multivectors (torch.Tensor) – Multivector inputs with shape (…, 16).
Returns:: pseudoscalars – Pseudoscalar component of multivectors with shape (…, 1).
Return type:: torch.Tensor
