This is a Monte Carlo sampling matlab programming, hope you can use it, enjoy!

在matlab绘图中绘制不同函数曲线的用户界面的m函数，奉献给大家！(Drawing graphics in matlab function curves of different user interface function of m, and dedication to you!)

说明：  BPSK仿真 仿真了在瑞利信道和加性高斯白噪声 下的调制和解调及误码率(The simulationof bpsk, input the signal in Rayleigh and awgn)

这个系统是基于matlab的双闭环直流调速系统，控制器使用了单片机，性能达到了设计要求。(The system is based on the matlab dual closed loop DC system, the controller uses single chip, the performance meets the design requirements.)

The exponential growth in the number of Photovoltaic (PV) system installations verifies that solar power technology has become one of the promising energy resources. This paper introduces new control scheme and converter topology for low to medium power PV applications. Proposed topology provides independent MPPT and power decoupling without the use of bulky electrolytic capacitors.

最短路这个说明倒不是说明函数的功能，只是声明一下函数中出现的问题。 shortest()函数没有问题，在secshortest中我希望只得到一条次短路（或几条roadcost()值相同的次短路），结果却出来好几条，我仔细检查了一下程序，应该没有什么问题。 因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。 有些奇怪 (short path)

it is the power system in matlab programing

实现viterbi译码功能的matlab程序(source code for viterbi decoding)

说明：  一维光子晶体传输矩阵法，matlab显示带隙图像。(One-dimensional photonic crystal transfer matrix method, matlab display images bandgap.)

抛物线拟合算法实现代码，已经通过测试可指直接运行(Parabola fitting algorithm code, has passed the tests can be run directly refers to)
