Module spatial 

Spatial similarity: dot products, angular (cosine), and Euclidean distances.

This module provides:

• Dot: Inner product of two vectors
• Angular: Cosine distance (1 - cosine similarity)
• Euclidean: Squared L2 distance
• VDot: Complex-valued dot product
• Roots: Scalar square root and reciprocal square root
• SpatialSimilarity: Blanket trait combining Dot + Angular + Euclidean

Traits

Angular

Computes the angular distance (cosine distance) between two vectors.

Dot

Computes the dot product (inner product) between two vectors.

Euclidean

Computes the Euclidean distance (L2) between two vectors.

Roots

Scalar square-root and reciprocal-square-root operations backed by NumKong’s exported kernels.

SpatialSimilarity

SpatialSimilarity bundles spatial distance metrics: Dot, Angular, and Euclidean.

VDot

Computes the conjugating dot product.
