使用Matlab语言完成《数值计算方法》中的Romberg（龙贝格）积分公式，程序可以根据用户输入的积分上下限、误差容限及表达式实现Romberg积分。(Using Matlab language to complete " numerical methods" in the Romberg (Romberg) integral formula, the program based on user input limits of integration, error tolerance and expression implementations Romberg integration.)

Wireless Sensor Networks have been proposed for a multitude of location-dependent applications. For such systems, the cost and limitations of the hardware on sensing nodes prevent the use of range-based localization schemes that depend on absolute pointto- point distance estimates. Because coarse accuracy is sufficient for most sensor network applications, solutions in range-free localization are being pursued as a cost-effective alternative to more expensive range-based approaches.

可以对数据进行双谱计算。适合对非平稳信号进行分析。(The data can be double-spectrum calculation. Suitable for non-stationary signal analysis.)

说明：  ARMA谱估计-AR参数估计的总体最小二乘法(ARMA spectral estimation-AR parameter estimation of the overall least square method)

一个可以进行图像区域特征识别的程序，很好用(An image area of feature recognition procedure is useful)

说明：  基于KL的人脸识别程序，但是缺少图像数据库，需要自己下载。(KL-based face recognition program, but the lack of image database, you need to download.)
