豪斯霍尔德QR分解及回代MATLAB代码，并用该方法解决线性方程组的实例(Howard Hopper QR decomposition and back substitution de MATLAB code, and use this solution to an instance of linear equations)

说明：  《统计信号处理基础 估计与检测理论》，该书本书是一部经典的有关统计信号处理的权威著作。全书分为两卷，分别讲解了统计信号处理基础的估计理论和检测理论。(&quot Statistical signal processing based estimation and detection theory&quot , the book This book is a classic authority on statistical signal processing work. The book is divided into two volumes, respectively, to explain the basis of statistical signal processing, estimation theory and detection theory.)

自己设计的陷波器，matlab实现，可以运行，代码注释清晰，非常适合初学者(Designed notch filter, matlab realize you can run code annotation clear, very suitable for beginners)

可以通过CST得到透射系数计算超材料的不对称传输系数(The transmission coefficient can be obtained by CST to calculate the asymmetric transmission coefficient of metamaterials.)

说明：  人工免疫算法(Artificial immune algorithm)

一些高阶统计量子程序，可以应用于心愿定位(Some higher-order statistics quantum procedure can be applied to wish positioning)

这个小程序是用matlab编写的可以用来计算截面N-M-PHI曲线的小程序(This little program is written in matlab can be used to calculate the cross section NM-PHI curve applet)

说明：  灰色理论认为系统的行为现象尽管是朦胧的，数据是复杂的，但它毕竟是有序的，是有整体功能的。灰数的生成，就是从杂乱中寻找出规律。同时，灰色理论建立的是生成数据模型，不是原始数据模型，因此，灰色预测的数据是通过生成数据的gm(1,1)模型所得到的预测值的逆处理结果。 此程序用来作灰色预测。 (Gray theory that the behavior of the system even though the phenomenon is dim, the data are complex, but it is after all, is orderly, there is a whole function. Gray number generation, that is, from the clutter to find out the laws. At the same time, the gray theory is to generate data model, rather than the original data model, therefore, gray forecast data to generate data through the gm (1,1) model by the inverse of the predictive value of the results. This procedure is used for gray prediction.)
