说明：  实现基2时域频域抽取fft算法，可输出运算后所得复序列的模值序列，并可记录显示计算所用时间(Achieve base 2 fft algorithm frequency domain extraction can be obtained after computing the output sequence of modulus of complex sequences can be used in the calculation time, records show)

用于模拟混凝土单元的弹塑性模型，并有损伤变量，在ABAQUS中umat中输入弹性模量，泊松比与屈服应力即可。(The elastic-plastic model for the simulation of concrete unit, and the damage variable in the ABAQUS umat enter the elastic modulus, Poisson' s ratio and yield stress can be.)

一个简单的LM算法程序，可以帮助你理解LM算法，还包括LM的解释(The neural network control method is used to control the unit step input of the controlled object)

说明：  satellite-tracking-opensource

使用Fortran涡度、散度、涡度平流、温度平流计算代码(Using Fortran vorticity, divergence, vorticity advection, temperature advection calculation code.)

自适应滤波器的LMS算法实现，主要实现滤波和算法的方法。(adaptive filter)

This is a simple mergesort code. It contains four directory. In the "lib" directory, there re two source code that can serve as timer and memory usage indicater. In the "src" directory, function "mergesort" can perform merge sort, while there s also a main function to execute it.

工程数学，积分变换，南京工学院数学教研组，内容包括傅立叶技术展开与拉普拉斯变换两大部分内容。(Engineering mathematics, integral transformation, Nanjing Institute of Technology mathematics teaching and research, including Fourier and Laplace transform technique to expand two parts content.)

摄影测量学中单像空间后方交会程序，matlab完成矩阵运算，程序简洁实用！(Photogrammetry single resection procedures such as space, matlab complete the matrix calculation, the program simple and practical!)

将一些标准数值与非数值算法集中封装在几个DLL中,需要用时可在VB/Delphi/C#中分别调用,这里提供了3个小程序,分别用于线性方程组求根、计算行列式的值、矩阵求逆。(Some standard numerical and non-numerical algorithm focus on packaging in several DLL, it is necessary to use when in VB/Delphi/C# Call, respectively, this provides three small programs, respectively, for the roots of linear equations, calculation of the value of the determinant, matrix inversion.)
