FFT

世界上开源的速度最快的FFT变换程序FFTW的说明文档，搜集了好久才找到，都是中文的，有助于对FFTW的使用。(Open source in the world s fastest FFTW FFT transform program documentation, gathered for a long time to find, are all in Chinese, help to the use of FFTW.)

利用c语言编写，编译成动态链接库而成的matlab整数规划工具箱,包含c语言源程序，(use of language, compiled DLL from the Matlab Integer Programming Toolbox contains language source c,)

说明：  一般的最小二乘通常是一次拿到全部的数据， 对所有数据进行统一优化计算得到模型系数。递推最小二乘是以一种递推的方式计算最小二乘，每次使用最新的测量值，来不断更新模型系数。(General least squares usually get all the data at one time, and perform unified optimization calculations on all the data to get the model coefficients. Recursive least squares is to calculate the least squares in a recursive way, each time the latest measured value is used to continuously update the model coefficients.)

根据试试数据 对变压器技术参数进行校核 利用的是最小二乘曲线拟合的方法(According to the data to try check technical parameters of the transformer is the least squares curve fitting using the method)

适用于Engine计算的经典PISO算法(the classic PISO algorithm for the Engine calculation )

Compaq Visual Fortran Error Messages，对于利用CVF编程的programmer是本很好的对照手册。(Compaq Visual Fortran Error Messages, programming, programmer for the use of CVF is a very good control of the manual.)

求人体信号的一个周期序列的CZT和FFT计算结果比较。是很好的程序，可以直观的看到效果。(Order to signal a cycle of the human sequence comparison CZT and FFT calculations. Is a very good program, you can see the visual effect. The body s signals.)

说明：  遗传算法反演程序源代码，主要反演瞬变电磁数据(Code for GA)

说明：  C++ SGP4 Satellite Library

Faran散射模型，能够计算液体中球形物体的散射声压(The Faran scattering model, able to calculate the scattering of spherical objects in the liquid sound pressure)
