弗洛伊德算法最短距离的实现，输入为邻接矩阵，输出为最短距离矩阵。(Freud' s realization of the algorithm for the shortest distance, enter the adjacency matrix output for the shortest distance matrix.)

这些代码可以用于产生一系列随机数，可以根据需要使用。(These codes can be used to generate a series of random numbers may be used as needed.)

四阶龙格库塔法，用C++编写，很有参考价值(Fourth-order Runge-Kutta method, written in C, a good reference)

数值分析中的高斯——塞德尔迭代算法的的C语言实现(Numerical Analysis of Gauss- Seidel iterative algorithm of the C language)

开发环境没有可选项，fortran90,Fortran_90_and_Computational_Science-_codes(Computational Science codes by fortran90 )

提供函数能进行1维2维的FFT，输入输出的序列长度应为2的整数次方倍(Provides functions can be one-dimensional two-dimensional FFT, sequence length input and output should be an integer power of 2 times)

基于全相位谱分析的相位差频谱校正法，结合了全相位FFT与传统FFT谱分析法。(Phase Difference Correcting Spectrum Method)

常微分方程数值解法，又是一个数值分析的常用算法(Numerical Solution of ordinary differential equations, numerical analysis is a common algorithm)

主要是关于一些数值计算中所要用到的头文件,希望对大家有所帮助(Mainly on the number of numerical calculation by the use of header files, I hope all of you to help)

说明：  LM算法的c语言实现 拟合的函数为gauss函数(Levenberg-Marquardt Method)
