The additional argument (PeakD) is roughly the ratio of the typical peak width to the length of the entire data record. Small values detect fewer peaks larger values detect more peaks. It effects only the starting values for the peak detection parameters. (This is just a quick way to set reasonable initial values of the peak detection parameters, rather than specifying each one individually as in example 5.

说明：  matlab的规范化（scale）函数，应用于svm的数据规范化，一般规范到（-1，1）或（0，1）(matlab standardized (scale) functions, used in data standardization svm, general specifications to (-1,1) or (0,1))
