分析声音波长频率，通过对声音的分析，以达到识别声音的效果(Analyze sound wavelength frequency, through the analysis of the sound to identify the effect of the sound)

matlab中用于进行fourier变换的GUI程序(matlab in fourier transform used for GUI program)

说明：  power算法，可用于求解大型矩阵特征值问题，对小型矩阵同样适用(power algorithm, can be used for solving large matrix eigenvalue problem, apply equally to small matrix)

基于聚类分析的核主成分分析，简单实用，希望对大家有帮助。(Based on cluster analysis of kernel principal component analysis, simple and practical, we want to help.)

使用matlab的小波分解和重建函数对24位的ADC采样数据进行小波变换和去噪，去噪使用阈值算法，阈值的选取具体使用了6种方法进行对比，对于不同信号其效果是不同的！把去噪后的信号和原始信号放在一个图中，使用不同颜色的曲线进行对比，效果可以很直观的表现。(Using matlab wavelet decomposition and reconstruction of the function for 24-bit ADC sampling data wavelet transform and denoising, denoising using the threshold algorithm, the threshold selecting specific methods used six kinds of contrast, the effect for different signals is different The! After the denoising signal and the original signal on a map using different colors to compare curves, the effect can be very intuitive performance.)
