Vector Algebra using SIMD instructions

Goal of this excercise is to learn how to implement and use 3- and 4-dimensional Vector Algebra using SIMD instructions

  1. Implement scalar product (invariant mass) between two Lorentz vectors
  2. Implement Lorenz boost transformation
  3. Measure speed-up

Code

in include:
SSEVec.h  SSERot.h
in examples:
SSEVec_t.cpp

Hints
