说明：  产生GOLD序列的主程序，和ss_mlsrs.m结合起来使用。(sequence generated GOLD program, and ss_mlsrs.m used in combination.)

用matlab做的单相boost PFC的仿真模型，功率11K，采用PI双闭环数字控制方法，波形较好。(Using matlab to do the simulation model of single-phase boost PFC power 11K PI double closed-loop digital control method, the waveform is better.)

Matlab是一个很好的大型数值计算软件。解释型的程序执行、即时的调试窗口、高效的矩阵运算、丰富的工具箱,使它成为了数值计算和科研工作的必备软件。虽然Matlab具有众多的优势,可是它的程序却很难完全摆脱Matlab环境运行,在界面功能上也效率低下,这些缺点我们在使用Matlab的同时,不免担忧自己的成果不能方便地对外发布。对Matlab的运行方式进行了分析,之后提出了Matlab和VC高级语言之间混合编程的方法,以及Matlab程序独立打包和如何提高Matlab程序的界面运行效率的方法。 更多还原 (Matlab is a nice large numerical software. Explain the type of program execution, real-time debug window and efficient matrix operations, rich toolbox, making it the numerical calculations and research work necessary software. Although Matlab has many advantages, but it is difficult to completely get rid of the program running Matlab environment, the interface functions inefficient, these shortcomings in the use of Matlab while we can not help but worry about their results can not easily be released. For Matlab operation mode are analyzed, and then propose a hybrid programming approach between Matlab and VC-level language, and Matlab program independent packaged and how to improve the operational efficiency of the Matlab interface procedures.

三相无源逆变的仿真，采用双闭环控制，PT调节器。(Passive three-phase inverter simulation, using the double closed loop control, PI regulator )

说明：  粒子群优化算法，弥补pso全局搜能力差，GA局部搜索能力差的不足(Particle Swarm Optimization (PSO) can make up for the deficiencies of poor global search ability of PSO and poor local search ability of GA.)

EEMD是针对EMD方法的不足,提出了一种噪声辅助数据分析方法。EEMD分解原理为:当附加的白噪声均匀分布在整个时频空间时,该时频空间就由滤波器组分割成的不同尺度成分组成。(EEMD)

有关通信系统中信道同步的问题，希望与大家切磋，多多指教。(the Channel Communication System synchronization issues, and we hope that the discussions and exhibitions.)

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 )
