This is some math library for Intel/AMD CPU. It uses the special SIMD instruction and Newton iteration math library run faster.

Project

AMaths A set of fast routines to calculate math functions using SSE&SSE2. The functions include sign abs sin cos tan sincos ect.. and is hundreds times better than what is achievable with lookup tables.

DPMatrix A matrix library using asm.The SPMatrix is Single-precision and DPMatrix is Double-precision. It run time is reduced by half than math.h

GPMatrix A matrix library using D3Dmath.

SML An advanced matrix library using SSE2.It support more functions than DPMatrix

D3DMath An advanced library include AMaths and a matrix library using SSE2

R3DMath This is an advanced library include math library and matrix library.It using AMaths as base math library.It using
_mm_rsqrt_ss instruction and newton iterationfor for sqrt functions.It also add AMD D3Dmath it faster than SSE2 in AMD CPU.
