获取windows和system32的默认完整路径，初学者可以学习参考一下(Access to windows and system32 default the full path, beginners can learn to refer to)

说明：  卡尔曼滤波器教程，matlab源码，每一步都有详细的说明，当作入门级教程很好(??????????????matlab?)

说明：  将低通模拟滤波器（LP）H(s)数字化为H（z）.(The low-pass analog filter (LP) H (s) figures into H (z).)

S-Function（系统函数）为扩展Simulink® 的性能提供了一个有力的工具。以下下节阐述了什么是 S-Function，为什么可以使用S-Function，以及怎样编写自己的S-Function。(S-Function (system function) for the expansion of the performance of Simulink ® provides a powerful tool. The following section describes what is under the S-Function, Why you can use the S-Function, and how to write your own S-Function.)

大坝底部渗透压的通量模型，本源码对大坝底部的渗透压进行建模，较好地反映了大坝底部的渗透系数对大坝的影响，文件头会设置一些参数(the enbankment and under which the volumn )

本程序是QPSK信号在瑞利衰落信道下的仿真，已经过本人验证，适合初学者(This procedure is QPSK signal simulation in Rayleigh fading channel, I have been verified, suitable for beginners)

加权网络的源代码，对于研究复杂网络模型很有用，可以参考哈^_^(BBV model-weighted network strength and weight distribution are the model of power.)
