金融学牛顿科兹求积分的方法的应用,证券投资组合的选择(Newton-Cotes formulas，Portfolio choice.)

说明：  用MATLAB实现半监督支持向量机，可用于分类问题中。(Semi supervised support vector machine is realized by MATLAB, which can be used in classification problems.)

基于粗糙熵和K-均值聚类算法的图像分割 (Based on Rough Entropy and K-means clustering algorithm for image segmentation)

matlab的steel金字塔小波分解源代码(matlab the steel pyramid wavelet decomposition source code)

主要介绍了七单元线形天线阵的波达方向估计（DOA）(Introduces the seven cell linear antenna array direction of arrival estimation (DOA))

This function takes the n time domain samples (real or complex) and finds the psd by taking (fft/n)^2. The two sided spectrum is produced by shifting the psd The array freq provides the appropriate frequency values for plotting purposes. By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db are set equal to -60db

实现了指纹图像的质量措施ocl(方向确定度),并以网格形式显示(Measures to achieve the quality of the fingerprint image ocl (direction determining degrees), and displays a grid)

FSK 信号的循环谱程序，验证了是正确的(The cycle of FSK signal spectrum procedure, verify the is correct)

说明：  用Matlab/simulink所实现的bpsk性能仿真系统，信道为AWGN信道。运行后，可以看到经过bpsk以后信噪比的增益。(using Matlab/Simulink BPSK achieved by the performance simulation system for the channel AWGN. After the operation, we can see the future through BPSK SNR gain.)
