see guys here is the code refer and take it

语音信号特征提取技术,PLP，MFCC,FFT等MATLAB程序。(plp mfcc)

his program calculates integral of f(x) using Composite Simpson rule.

bessel函数计算方法，源于matlab算法书中，比较权威(bessel function, method of calculation from the book matlab algorithm to compare the authority of)

说明：  用迭代法计算Fibanacci数列的第n项(Iteration calculation Fibanacci the first n items of data series)

matlab programmer plc

用于数据信号去噪，非常好用，值得强烈推荐，强烈推荐(For data signal denoising, very easy to use, highly recommended, highly recommended)

已知消息信号为一个长度为8的二进制序列；载波频率为 ，采样频率为4KHz。编程实现一种调制、传输、滤波和解调过程。(Known message signal is a binary sequence with a length of 8 the carrier frequency, the sampling frequency of 4KHz. Programming a modulation, transmission, filtering, and demodulation process.)

包括单边带、双边带、载波抑制及四倍频,有借鉴意义哦，AHP层次分析法计算判断矩阵的最大特征值。( Including single sideband, double sideband, suppressed carrier and quadruple, There are reference Oh, Calculate the maximum eigenvalue judgment matrix of AHP.)

说明：  使用EEMD对故障信号进行分解，提取不同imf的能量熵，有数据可直接运行。(EEMD is used to decompose the fault signals, extract the energy entropy of different IMF, and the data can be operated directly.)
