I know this is going to sound terribly naive, but how does one define DNDEBUG?  I am using VS.NET and Borland Enterprise 6.0.  Thanks!

  Oh yeah. NDEBUG really makes a difference. Now dense matrix 
  performance rocks. I was confused a bit, cause usually special flag 
  is used to compile debug version, not release one. But it works too 
  as long as one knows about the trick.

  I will test more with sparse matrices.
