ADO查询获取的结果输出followind datastruct： myOutput.data myOutput.columnnames 第一个包含一个二维细胞矩阵，与列名第二单元阵列。 此函数使用此信息来创建一个没有细胞集。 (the ADO query fetch result outputs the followind datastruct: myOutput.data myOutput.columnnames The first contains a 2d cell matrix, the second a cell array with column names. This function uses this information to create a dataset without cells.)

说明：  内维尔插值在很多学科都能用到，相信对大家有用！(Neville interpolation can be used in many disciplines, I believe it would be useful!)

guassian sobel filter for image processing

本程序是有限时域差分源程序，有详细注解，方便学习理解。(This program is a limited time domain difference source program, has detailed notes, easy to learn to understand. )

认知无线电频谱感知中，用能量检测算法实验频谱感知(Cognitive radio spectrum sensing, energy detection algorithm experimental spectrum sensing)

被控对象为G(S)=400/（s*s+500s）,首先运行模糊控制器程序chap4_2.m,并将模糊推理系统保存在a2中，然后运行模糊控制SIMULIK程序。位置指令为0.5sin（10t）,simulink见chap4_3(Controlled object is G (S) = 400/(s* s+500s), first run the fuzzy controller program chap4_2.m, and stored in a2 fuzzy inference system, and then run the fuzzy control SIMULIK program. Position command is 0.5sin (10t), simulink see chap4_3)

此程序是在假设已知波达角的情况下进行仿真验证的实验，零陷music波速成形。(This procedure is known in the hypothetical case of DOA conducted simulation experiments, velocity forming nulls music.)

主要用于辐照图变化下，对最大功率的寻求，代码基本没问题，希望有所帮助(It is mainly used to seek the maximum power under the change of irradiation pattern.)
