傅里叶变换功能的实现，虽然是非常见得的频率成分，但是还是实现了基本的傅里叶变换功能，并不是matlab自带的fft函数。实现了频谱分析可视化。(Fourier transform function, although it is very frequency components appear, but still achieve the basic function of the Fourier transform, comes not matlab fft function. Achieve a spectral analysis visualization.)

process bench marking code

实现图像分类，支持向量机原始优化算法SMO(Image classification, the original optimization algorithm SMO support vector machine)

神经网络修改BP辨识算法，用于辨识复杂的非线性系统，相对传统BP算法，具有计算快等优点(Modify BP neural network recognition algorithm for identification of complex nonlinear system, compared to the traditional BP algorithm has the advantages of quick calculation)

MATLAB编程实现DFT波束形成，64个阵元(MATLAB programming DFT beamforming)

source code for OCR in matlab using NN

这是计算三维dihedral的散射程序，对研究电磁散射的同行很有用(This is the calculation of the dihedral scattering of three-dimensional procedures, the study of electromagnetic scattering useful peer)

lms算法，下载后自己运行即可，很方便的。我也是刚开始学(lms algorithm, you can download to run their own, very convenient. I am also just beginning to learn)

利用小波变换多尺度分析的特性,在小波域的各个尺度上选取不同的阈值对基本的频域谱减法进行改进,并且根据清浊音各自不同的特点,在去噪过程中加以分离,保留了语音中的清音成分,使语音更加饱满。(The use of multi-scale wavelet analysis of the characteristics of the individual in the wavelet domain scale threshold select a different frequency domain of the basic spectral subtraction to improve and, in accordance with their respective Qingzhuo sound different characteristics, in the denoising process be separated from the retained voice of the voiceless in the composition, more full of voice.)
