应用matlab进行数独解密的算法和教程，英文版，来自matlab创始人(The Userguide to use matlab to solve sudoku)

可用于转子的动力学分析，包括固有频率的计算和振型的输出。(Can be used for rotor dynamics analysis, including the calculation of the natural frequency and vibration mode output.)

一个故障诊断的程序，采用了多种方法，将故障时刻检测了出来，并进行了比较(A fault diagnosis program, using a variety of methods, fault detection out moments, and compared )

说明：  用于检测微弱信号的Duffing系统，这是我的毕业设计一部分，因为我做的时候也曾求取过很多资料，但是并没有找到，因此在我完成之后，上传这个代码，希望这个能帮助别人。 里面还有后续做的GUI界面实现的Duffing振子检测功能，可检测信号幅值和频率。(The Duffing system for detecting weak signals, this is part of my graduation project, because I also asked for a lot of information when I did it, but it was not found, so after I finished, upload this code, I hope this can help others.)

linear SRC for sample rate conversion

数字滤波器的实现，矩形窗、汉宁窗、海明窗、布莱克曼窗等窗函数 (The realization of digital filters, rectangular window, Hanning window, Hamming window, Blackman window functions such as window)

说明：  毕业设计，OFDM系统仿真，并使用多种编解码和纠错码(Graduation Project, OFDM system simulation, and use a variety of codecs and error-correcting codes)
