vector quantizer for matlab. very simple

another vector quantizer for matlab. maybe this one is better

实现已知训练序列的矢量量化器（LBG）算法。初始码书从训练序列每隔五个样本选取一组-Achieve a known training sequence of the vector quantizer (LBG) algorithm. The initial codebook from the training sequence every five samples to select a group of
