说明：  在模式识别应用中，用分支定界法(branch-and-board method)进行特征的选择。该程序在matlab环境下实现了该算法，以从六个特征中选择两个最佳特征为例(In pattern recognition applications, using branch and bound method (branch-and-board method) to carry out the characteristics of choice. The program in the matlab environment to achieve the algorithm to select from the following six characteristics of the best features of the two as an example)

程序计算仿真偏馈抛物面天线的特性如远场方向图 波束宽度 增益 极化等等(Program simulation calculation of offset parabolic antenna characteristics such as far field pattern beamwidth gain polarization etc.)

Welch功率谱密度是用改进的平均周期图法来求取随机信号的功率谱密度估计值。Welch法采用信号重叠分段、加窗函数和FFT算法等计算一个信号序列的自功率谱估计(PSD如上例中的下半部分的求法)和两个信号序列的互功率谱估计（CSD）。MATLAB信号处理工具箱函数提供了专门的函数PSD和CSD自动实现Welch法估计，而不需要自己编程。(method of power spectral density plot )

灰色模型算法，通过改进之后，考虑了之后的误差处理，减少了因为数据变化太大而引起的预测不准确的现象。(Gray model algorithm, improvements, after taking into account the error handling, reduced because the data has changed so much caused by inaccurate forecasts phenomenon.)
