用matlab求伪Wigner-Ville分布

说明：  Project on cryptography related to digital image processing. if anyone wish to perform then can download it. reference papers are also included.

说明：  32位变量移位操作，输出到界面。联合体变量是公用一块内存，所以对其中一个变量操作会影响其他变量。(32-bit variable shift operation, output to the interface.)

中科大fortran讲义，内容很不错！！！！(USTC to fortran handouts, the content is very good! ! ! !)

断裂的K文件,用于lsdyna，裂纹扩展，前处理用ansys或者hypermesh.(The broken K file is used for LSDYNA, crack propagation, pretreatment with ANSYS or hypermesh.)

机器学习，python实战。里面有很多常用的算法和其相应的实现，很好的机器学习书籍，带源码(Machine learning, python actual combat. There are many commonly used algorithms and their corresponding implementation, good machine learning books, with source code.)

说明：  Eric Matthes 编著的Python编程从入门到实践配套源码。(Eric Matthes compiled Python programming from entry to practice supporting source code.)

说明：  滑模控制器的程序，用M文件和model实现，很有参考价值(Sliding mode controller procedures, with M files and model achieved a good reference)

说明：  Nehe大神的OpenGL教程，内附48节课的课程源码~希望对学习OpenGL的人有所帮助(OpenGL_Course_NeHe,Nehe's OpenGL course, which contains the source code of 48 courses. I hope it can help people who study OpenGL)

说明：  3D地形显示对应charpter2第一个demo ，编译通过(The terrain is created in the form of triangle fan, which has been compiled and passed)

这是一个带有FEAPPV的测试库。有限元分析程序（FEAP）用有限元法求解一般问题。问题大小由每台计算机的主内存量控制。(This is a test repository with FEAPpv. Finite Element Analysis Program - (FEAP) for solution of general problem classes using the finite element method. Problem size is controlled by the amount of main memory in each computer.)
