EX3

This abstract class represents an entry in the ConstantPool. Specific types of entries are subclassed from it.

对STL文件进行智能切片，使切片的质量提高(The STL file is smart, so that the quality of the slice is improved.)

一种降维方法，是非线性降维方法，也是非监督降维方法。(A dimensionality reduction method is a nonlinear dimensionality reduction method and an unsupervised dimensionality reduction method.)

说明：  pso 的实现 应用了c#进行编程 还含有带约束的MATLAB的pso(pso implementation of the application of c# programming with constraints also contains MATLAB-pso)

matlab画图的一些命令，可以学习学习 matlab画图的一些命令，可以学习学习(some commands for how to plot)

Simulation of basic circuit eletric

同相中相环路，用于符号同步估计。采用simulink设计(PLL for bit/symbol synchronization )

首先对图像进行非线性灰度变换滤除噪声，然后利用最大类间方差阈值技术对处理后的图像进行二值化处理，最后利用积分投影定位人眼(First to utilize non-linear gray-scale transformation to filter out noises, then adopts the between-cluster variance threshold segmentation method for image binarization processing, finally using integral projection technology to pinpoint the human eye)

采用matlab解微分方程，讲解比较详细，值得看看(Using matlab for solving differential equations, to explain in more detail, is worth a look)

设计一个采用 2ASK（OOK）调制的数字通信系统，给定载波频率为码元速率的2倍，产生二进制随机数据，并仿真其对应的 2ASK 调制波形，分析其频谱。所产生的调制波形加入不同信噪比的白噪声，再观察其波形和频谱变化。(Design of a use 2ASK (OOK) modulated digital communication system, a given carrier frequency is twice the symbol rate, to generate a random binary data, and simulate its corresponding 2ASK modulation waveform, the spectrum analysis. Modulated waveform generated by white noise with different noise ratio, and then observe its waveform and spectrum changes.)
