基于matlab的锁相环（PLL）仿真源代码(Matlab based on the phase-locked loop (PLL) simulation source code)

可以进行直方图计算，也可以进行灰度运算，可以实现图像的变换操作(Histogram can be calculated, it can be gray-scale operation, the image transformation operation can be achieved)

Buck modeling Matlab/Simulink

着重介绍了OFDM 系统 中的峰值平均功率比（PAR）问题，给出了峰值平均功率比的定义以及高PAR 产 生的原因和它带来的问题，并且分析了OFDM 系统内PAR 的分布，最后对国内 外各种降低PAPR 的方法进行了简单介绍。(Focuses on the OFDM system The peak to average power ratio (PAR), and gives the definition of peak to average power ratio and high PAR production Health reasons and problems it brings, and the analysis of the distribution of the PAR of OFDM system, the last of the domestic A variety of methods to reduce PAPR outside a brief introduction.)

4步标定法，主要是实现计算机数字图像处理摄像机的标定，操作简单，比较实用(4-step calibration method is to achieve a computer digital image processing camera calibration, easy operation, more practical)

说明：  很强大，用于优化的算法，准确度高，速度快(Very good, algorithm for optimization, high accuracy, fast speed)

是一篇关于复杂网络的论文这个文档还是有点价值的(Is a complex network of papers on this document is still a bit value of)

This is a boiling tutorial for fluent
