title: What's the fastest vector/matrix math library in C for iPhone game?
body: <p>As the title, I'm finding vector/matrix library in C optimized for iPhone/iPod processors.
  Or just generally fast.</p>
  
  <p>---(edit)---</p>
  
  <p>I'm sorry for unclear question. 
  I'm looking for fast lib for commercial games for iPhone/iPod. So GPL lib cannot be used.</p>
  
  <p>However, I'll stop finding fastest lib, it maybe meaningless.</p>
