Kalman filter function that remove noise from speech

说明：  一个非常不错的savitzkyGolay工具包 并有详细的帮助说明 功能强大(SavitzkyGolay a very good kit and a detailed description of the powerful help)

This book is : Basics of MATLAB and Beyond - Andrew Knight, you can use this book with file code i uploaded before. Well done !

First use EEMD to decompose the original singal to get IMFS,then use FFT to analyse the each IMF,combine EEMD with FFT to get clearer analytic results.

使用有限元法求解一维伯努利梁的位移和应力算例。(an example of sovlving Euler-Bernoulli beam problem with FEM)

Abstract - In this paper, proposed an efficient method of converting speech codec formats between G.723.1 and G.729А. The proposed method is composed of four steps: LSP conversion, pitch conversion, adaptive codebook search and fixed codebook search. Subjective results shown that the proposed method has shorter delay than classical tandem method.

matlab上倒谱的两种实现方式。一个是调用rceps（）函数来实现，另一个是根据定义来实现。两种方法画出的倒谱图一样。 附件中包含要处理的数据，该数据为加速度数据。(matlab on the cepstrum of two implementations. One is called rceps () function, and other is by definition to achieve. Draw the two methods as the inverted spectrum. Annex contains data to be processed, the data for the acceleration data.)
