这是一个用于一维等离子体粒子模拟的Fortran程序。(This is a one-dimensional plasma particle simulation for Fortran programs.)

对离散点进行多项式拟合，不同于传统多项式拟合高次出现病态，此程序可以拟合高阶多项式( ORTHOFIT Fit polynomial to data. YS = ORTHOFIT(X,Y,N) smooths/fits data Y(X) in a least-squares sense using a polynomial of degree N and returns the smoothed data YS.)

线性规划matlab算法，包括单纯形法，修正单纯形法，大M法，变量有界单纯形法。(Matlab algorithm of linear programming, including the simplex method, revised simplex method, big-M method, the variable bounded simplex method.)

齿轮传动参数测定和公法线公差计算，变位直齿圆柱齿轮参数测定(Determination and the normal line of the gear transmission parameter tolerances calculation)

Fitting curve distribution function拟合曲线分布函数(Fitting curve distribution function)

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!)

大量数值分析常见算法的源程序 如解方程组 插值等 可以用浏览器打开的HTM文件，内部使用C开发(A large number of numerical analysis algorithms common source such as the solution of equations interpolation can be used to open the browser)

说明：  巴特沃斯、切比雪夫I和椭圆滤波器设计的源程序！非常难得！ 简洁的C语言编写(Butterworth, Chebyshev I and elliptic filter design of the source! Very rare! Concise C language)

Fortran program which can be used to solve linear system

这是一个数值计算Fortran程序，将矩阵进行奇异值分解，SVD.txt存放待分解的矩阵，u.dat,v.dat为分解后的左右矩阵，qiyizhi.dat和qiyizhi0.dat为得到的奇异值。(This is a numerical Fortran program matrix singular value decomposition, SVD.txt store to be factored matrix, u.dat, v.dat about decomposition of the matrix, qiyizhi.dat and singular value obtained qiyizhi0.dat .)
