function Px=overlay(N,omega,A,sigma,num) OVERLAY Forms multiple power spectral density estimates. ------- USAGE Px=overlay(N,omega,A,sigma,num) Calculates the periodogram using an ensemble of realizations of a process consisting of a sum of complex exponential in white noise. N : length of the signal omega : vector containing the sinusoid frequencies A : vector containing the sinusoid frequencies sigma : the variance of the white noise num : size of the ensemble (number of periodograms)

在视图中使用CWindowDC在整个窗口进行绘图，C++精选学习源码，很好的参考资料。(For drawing in the window using CWindowDC in the view, select learning C++ source code, a good reference.)

产生BPSK调制信号，通过高斯信道，接收端解调，计算误码率(BPSK modulated signals generated by Gaussian channel, the receiver demodulation, bit error rate calculation)

奇异值分解（SVD）的MATLAB仿真性能分析(Singular value decomposition (SVD) of the MATLAB simulation performance analysis)

基于LBP的人脸识别技术的代码，用MATLAB程序实现(LBP face recognition technology-based code)

Hyperspectral Image Index Analysis

使用支持向量机进行非线性回归，得到非线性函数y=f(x1,x2,…,xn)的支持向量解析式，求解二次规划时调用了优化工具箱的quadprog函数。本函数在程序入口处对数据进行了[-1,1]的归一化处理，所以计算得到的回归解析式的系数是针对归一化数据的，仿真测(Using support vector machines non-linear regression)

This code is very useful to detect key-points, extract features those key-points. This code is useful to detect SIFT key-points
