mat itpp::vqtrain	(	Array< vec > &	DB,
		int	SIZE,
		int	NOITER,
		double	STARTSTEP = 0.2,
		bool	VERBOSE = true
	)

Function for vector quantization training.

The following code illustrates how the VQ can be trained.

  VQ Quantizer;
  mat A;
  Array<vec> database;

  // read vectors into database somehow
  ...

  // train a vq
  A = vqtrain(database, 1024, 1000000);
  Quantizer.set_codebook(A);
