这是中国数学建模中编程交流上搜索算法内容，里面提供了很多搜索算法的例子(This is the exchange of mathematical modeling in the programming content on the search algorithm, which provides many examples of search algorithms)

单用户MIMO以及多用户MIMO的检测程序,包括最大似然检测,最小均方误差检测等的matlab实现，以及MIMO_OFDM主要程序(Single-user MIMO and multi-user MIMO testing procedures, including maximum likelihood detection, minimum mean square error detection matlab realize and the main program of MIMO_OFDM)

灰色预测模型，适合对指数型增长的模型进行中短期预测，如人口增长模型(Grey forecasting model of exponential growth model is suitable for short-term earthquake prediction, such as population growth in the model )

GUI系统尽心Radon变化，所谓Radon变换，就是将原始图像变换为它在各个角度的投影表示。 (Radon dedicated GUI system changes, the so-called Radon transform, the original image is converted to its projection showing all angles.)

matlab统计分析案例，经典教材，值得好好学习，对数模很有帮助(Matlab statistics, which is quite worth reading and is beneficial to mathmatical learning.)

this is a file about probabilioty data association

本例用matlab语言实现了8dpsk的编解码及通过awgn信道的仿真。采用蒙特卡罗仿真法，得到误码性能，绘制曲线。可用于算法研究或课程学习。(cases using the Matlab language of the codec 8dpsk and awgn channel through the simulation. Using Monte Carlo simulation, to be error performance, drawing curves. Algorithms can be used to study or courses.)

These are digital modulation source codes.

normalized threshold vs the probability of false alarm in radar system.

声谱图+共振峰,有中文的注解, 像Praat(spectrogram+ Formant, Code has Chinese comments)
