说明：  二分法检索（binary search）又称折半检索，二分法检索的基本思想是设字典中的元素从小到大有序地存放在数组（array）中， 　　首先将给定值key与字典中间位置上元素的关键码(key)比较，如果相等，则检索成功；(Dichotomy search (binary search), also known as binary search, the basic idea of ??dichotomy is set to retrieve the dictionary from small to large elements stored in an orderly array (array), the first key the given value on the middle element of the dictionary The key code (key) comparison, if they are equal, then the retrieval success )

XFEM扩展有限元模拟二维裂纹动态扩展，由哈弗大学一个研究小组开发，非常值得学习(XFEM extended finite element simulations of two-dimensional crack dynamic propagation, developed by a team at Harvard University, is worth learning)

认知无线电主用户信号为BPSK信号在不同信噪比下的检测概率和虚警概率(Cognitive radio primary user signal is BPSK signals in different SNR detection probability and false alarm probability)

Evaluate frequency spectrum of signals

说明：  几种不同方式编制的傅立叶变换程序对比，可帮助大家对傅立叶变换有更深刻的理解。(Prepared in several different ways Fourier transform procedure compared to the Fourier transform can help you gain a deeper understanding.)

说明：  这有关于微分方程求解 的 比较实用的 用Matlab 进行编程实现(This is about more practical for Solving Differential Equations with Matlab, programming)

mosaic.rar拼接技术，matlab 源程序，希望有所帮助，(mosaic.rar splicing technology, matlab source code, hope that helps,)

说明：  二进制差分编码解码，二进制差分相移键控二进制幅移键控，二进制相移键控，二进制频移键控最小频移键控的调制与解调(Differential encoding and decoding binary, binary differential phase shift keying binary amplitude shift keying, BPSK, binary frequency shift keying Minimum Shift Keying modulation and demodulation)
