Overview ¶

Package math provides SIMD-accelerated mathematical transforms for the dataset engines.

Slice transforms apply a transcendental function element-wise to an entire slice using SIMD vectorization (AVX-512, AVX2, NEON, or scalar fallback).

Vector-level functions operate on individual SIMD register vectors for use in custom compute kernels.

All functions are generic over hwy.Floats (float32, float64, Float16, BFloat16) and provide ~4 ULP accuracy.
