本代码为音频分析工具包，可配合学习葛哲学，陈仲生等人著作的《Matlab时频分析技术及其应用》一书。

本文采用的是先对脉搏波进行经验模态分解，产生一组内在的模函数，每一种模态对应一种物理状态，之后使用ＨＴ得出瞬时的频率和振幅，进而得到边际谱-In this paper, is the first of the pulse wave empirical mode decomposition, resulting in a set of intrinsic mode function, each mode corresponds to a physical state, followed by the use of HT derived instantaneous frequency and amplitude, and thus to be marginal spectrum
