frotran输入矩阵自编小程序，可以生成任意大小矩阵，并写入制定文件(frotran input matrix composing small program that can generate any size matrix, developed and written documents)

最小二乘曲面拟合程序（m文件），对一组三维数据z=f(x,y)拟合，成为关于x和y的多项式(least squares fitting procedure Surface (m), a group of three-dimensional data z = f (x, y) fitting, be on the x and y polynomial)

本人编写的基于最小二乘法的圆拟合程序，可直接下载使用。(I prepared the least squares method based on circle fitting procedures, can be directly download.)

河口、海洋高低潮位调和分析与预报程序，根据方国洪的书编制。(Estuaries, marine high and low tide harmonic analysis and prediction program)

本程序是基于非等距节点的正交多项式的最小二乘法拟合算法，该算法已经在vc++6.0下调试通过，经多次验证，本算法的拟合误差较小。(This procedure is based on equidistant nodes of non-orthogonal polynomial least squares fit algorithm, which has been in vc++6.0 through debugging, after repeated verification, the algorithm of fitting error is small.)
