素数的判定，miller-rabin，sol-str,leman,fermat等。都可以运行，下完自后自己稍微改改就可以用。(Primes judgment, miller-rabin, sol-str, leman, fermat so on. Can run is finished after their own little changed since it can be used.)

一维云发生器，matlab编写，比较好用(the yun generator which is good)

Matlab通信仿真原理，中文的，是一本入门级别的，写的很详细，也有很多详细的例子(Matlab Communication simulation theory, in Chinese, is an entry-level, written in great detail, there are many detailed examples)

Dab simulation using convolutional encoding!! punctured convolutional code!!

Code gauss_seidel, Jacobi and Sor, differences in the implementation of numerical methods divided.

3DFDTD用来计算三维光子晶体在入射波照射下的透过率情况(3DFDTD used to calculate the three-dimensional photonic crystal in the case of incident radiation transmittance)

该损伤模型通过 商用有限元软件ABAQUS /Explicit 的用户子程序VUMAT 实现，并使用该模型对碳纤维增强环氧树脂 复合材料层合板在横向低速冲击作用下的损伤和变形行为进行预测分析． 数值仿真的结果与试验结 果进行了比较，吻合良好，验证了该模型的有效性．(Through coding user subroutine VUMAT of finite element software ABAQUS /explicit， and applied the model to an example，carbon fiber reinforced epoxy composite laminates under low velocity impact，the prediction for damage and deformation were good agreement with the experimental results．)

本文提供了彩色图像的简单降采样，缩小，及方法功能，以及图像成倍给打上马赛克的matlab有效可执行代码，希望对大家的学习有帮助。(This article provides a simple down-sampled color image, narrow, and functional method, and an image mosaic matlab doubled to effectively marked executable code, we hope to help learning.)
