轮轨接触点扫描方法，用扫描的方法计算求得任意轮轨型面的轮轨接触点(Wheel-rail contact point scanning method, the method of calculation obtained by scanning any type of wheel and rail wheel-rail contact point surface)

这是基于傅里叶变化的压缩感知稀疏分解方法，使用的是匹配追踪算法，对初学者很有帮助(This is based on Fourier transform of compressed sensing sparse decomposition method, using the matching pursuit algorithm, useful for beginners)

16v280柴油机总切向力计算过程的matlab程序，可计算一个循环的总切向力(16v280 diesel matlab program, the total shear force calculation process computable a loop the total tangential force)

AOA定位，MUSIC算法仿真，值得一看(AOA location, the MUSIC algorithm simulation, worth a visit)

本实验先利用Mathematica求解非线性方程(组),探索不动点的性质 再利用MATLAB探索Koch分形的性质.(In this study, the first use of Mathematica for solving nonlinear equations (group), to explore the nature of the fixed point re-use of MATLAB to explore the nature of the Koch fractal.)

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)

基于matlab编写的图像滤波程序，包括均值滤波和中值滤波，并给出了处理后的图像(Image matlab image-based filtering process, including mean filter and median filter, and gives the treatment)
