确定矢量的长度 length
只有当几个分矢量在一直线上，那么表示其和的矢量长度才会等于这些分量的长度和或它们的差。
Only if the component vectors are on a straight line will the length of the vector for the sum be equal to the sum of the lengths of these components or to their difference.
只有当几个分矢量在一直线上，那么表示其和的矢量长度才会等于这些分量的长度和或它们的差。
Only if the ponent vectors are on a straight line will the length of the vector for the sum be equal to the sum of the lengths of these ponents or to their difference.
分析和实验结果表明：若采用动态时间规正算法(DTW)，识别时间与特征矢量长度的平方成正比关系。
Both analysis and experiments show that the recognition time is proportional to the square of the length of the feature vector, if dynamic time warping (DTW) algorithm is employed in recognition.
