一个用matlab中的GUI编写的倒计时程序，可用于GUI初学者学习使用(GUI with matlab in a countdown to the preparation procedure can be used for beginners to learn to use GUI)

一个数学公式的简单应用在matlab中的实现，绝对值及平方等(Simple application of a mathematical formula in the matlab implementation, such as absolute value and square)

说明：  自相关函数和互相关函数的matlab计算和作图，这个是信号分析里的概念，他们分别表示的是两个时间序列之间和同一个时间序列在任意两个不同时刻的取值之间的相关程度。(Self correlation function and cross-correlation function of matlab calculation and drawing, this is a concept in signal analysis, they are respectively represent the is between any two different time value relevance of the two time series and the same time series.)

根据条形光波导折射率数据，分别针对宽高比a:b为1:1与2:1两种情形，设计平板波导色散图(Planar waveguide dispersion map )

MATLAB是美国MathWorks公司出品的商业数学软件，用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境，主要包括MATLAB和Simulink两大部分。(MATLAB is a very popular language for technical computing used by students, engineers, and scientists in universities, research institutes, and industries all over the world.)

LCMV优化设计阵列处理信号，本科毕设要求参见标准测试模型，在matlab R2009b调试通过，包含特征值与特征向量的提取、训练样本以及最后的识别，BP神经网络用于函数拟合与模式识别。( LCMV optimization design array signal processing, Undergraduate complete set requirements refer to the standard test models, In matlab R2009b debugging through, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, BP neural network function fitting and pattern recognition.)

基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.(OFDM-based wireless broadband system simulation It contains mainly two parts, ie link-level simulator and system-level simulator.Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx .
