说明：  直接法求双谱，间接法求双谱，还有基于AR模型法求双谱。程序里面还提供了一种很方便的求对角线谱的方法，大家可以借鉴。总之，你下载了，绝对不后悔的。(Direct method bispectrum, bispectrum Indirect Method, as well as AR Model Method based on dual spectrum. Program which also provides a convenient way to find the diagonal spectrum, we can learn from. In short, you download, and definitely do not regret it.)

说明：  matlab编写的局部轨道不平顺，交点型轨道不平顺的（垂向，水平，方向，轨距不平顺）。(matlab prepared local irregularity, intersection type track irregularity (vertical, horizontal, direction, gauge irregularity).)

ANSYS FE procedures and 3D models for thermal and mechanical simulation of both Laser and TIGwelding processes are presented

说明：  配电网潮流计算，PQ分解法，IEEE30节点验证。(Distribution power flow calculation, PQ decomposition method, IEEE30 node validation.)

Simple MSK modulation

批量数据处理，内含有非线性拟合代码、数据拟合、非线性拟合、非线性回归分析(Matlab batch data processing Matlab general nonlinear fitting code, data fitting, nonlinear fitting, nonlinear regression analysis )

6 sigma设计用源程序 (Design for six sigma ORTHOGONAL ARRAY TOOL V52.XLS)

说明：  这是用MATLAB编写的规划问题的程序，用的着的请参考。(This is prepared by using MATLAB programming procedures, please use the reference.)

对于39节点配网潮流计算，用前推回代法编写的matlab程序，加压后直接运行(For the 39 node distribution network power flow calculation, using forward and backward substitution method to write matlab program, run directly after pressurization)

100个Matlab的编程实例，涉及图形应用、界面设计、图形处理、数值分析等内容，很实用，辛苦整理，与大家交流学习。(100 Matlab programming examples involving graphics, interface design, graphics, numerical analysis and other content, very practical, hard finish, and to share learning.)
