批量读写配置文件 　本例程使用复制组件，复制所需要的窗口组件，并且配合组件的 标记、取标记组件、取事件组件，让组件互相关联互动。这样做的好 处是：设计时窗口组件很少，节省设计时间，节约空间，便于代码的 后期升级维护。(Read and write configuration files in batches)

说明：  认知场景下加性高斯噪声对于误码的影响，已经干扰问题的转换源码(Cognitive scenarios for the additive error of Gaussian noise has been the conversion source interference problem)

说明：  rc滤波器的设计，很详细的过程，从原理到代码都有(rc filter design, a very detailed process, from theory to code all)

环节离散化非线性仿真程序.这是课程学习中使用的例程，希望对大家有用。(Aspects of discrete non-linear simulation program. This is a course of study used in the routine, the hope that useful.)

Kalman Filter and peridogram

一本介绍卡尔曼滤波的基础书籍，其中包含大量的具体应用。(An introduction book for Kalman Filter)

粗糙集属性约简的matlab小程序以及一些可读文献~~~~(Rough set attribute reduction procedures as well as some small matlab readable literature ~ ~ ~ ~)

matlab编程对信号进行相关卷积等运算，并基于功率谱计算原理进行编程，加深对此理解 (the matlab programming related convolution operation signals and power spectrum calculation principle-based programming, to deepen this understanding)
