FFT Fourier transform code

In his 1960 famous publication (“A new approach to linear filtering and prediction problems”, Trans.ASME J. Basic Engineering., vol 82, March 1960, pp 34-45), Rudolf Kalman based the construction of the state estimation filter on probability theory, and more specifically, on the properties of conditional Gaussian random variables. The criterion he proposed to minimize is the state vector covariance norm, yielding to the classical recursion : the new state estimate is deduced from the previous estimation by addition of a correction term proportional to the prediction error (or the innovation of the measured signal).

MFCC：Mel频率倒谱系数的缩写。Mel频率是基于人耳听觉特性提出来的，它与Hz频率成非线性对应关系。Mel频率倒谱系数(MFCC)则是利用它们之间的这种关系，计算得到的Hz频谱特征。(Speech signal feature extraction)

本程序主要通过EMD算法，多级分解原始信号X，结果为多个IMF和一个residue。(This program is mainly by the EMD algorithm, multi-level decomposition of the original signal X, the results is multiple the IMFs and a residue.)

针对单一的一个酶促反应，可以得到不同的反应物质在盒子空间中的粒子分布状态，对其他化学反应的研究同样适用。(For a single enzymatic reaction, the particle distribution state of different reaction substances in the box space can be obtained, and the study on other chemical reactions is also applicable.)
