车辆系统动力性半车模型根据运动学方程计算系统响应的功率谱密度和频率响应函数的源程序(Vehicle system dynamic half-car model according to the kinematic equation system response power spectral density and frequency response function of the source)

高斯迭代算法基本程序，用于求解矩阵方程，对初学者很有帮助(Gauss iterative algorithm for solving the matrix equation, useful for beginners)

matlab提取图像质心和主轴，使用的是matlab图像处理工具箱函数(extraction matlab image centroid and the spindle, using matlab image processing toolbox functions)

DBPSK，包括误码率统计和误符号率统计(DBPSK, including bit error rate and symbol error rate statistics Statistics)

利用第二代小波变换———提升小波变换,为第一代小波变换提供了一种新的更快速的实现方法,使得其构造不再 依赖于Fourier 变换构造,可以实现所有的第一代小波变换,提升方案把此变换过程分为分裂、预测和更新3 个阶段。(--- Second generation wavelet transform using lifting wavelet transform, for the first generation wavelet transform provides a new, more rapid implementation method, so its structure is no longer dependent on the Fourier transform structure, can achieve all of the first generation wavelet transform, enhance the program to the transformation process is divided into split, predict and update the three stages.)

This code calculate the steady seepage fo a concrete dam. The program is written in a manner that you can easily change the problem information. To understand how the program works, run main.m then follow the mentioned subroutines (.m files). There is enough comments in all .m files.
