最小二乘法回报潮汐水位，根据dooson数回报潮汐，并计算调和常数，余水位，高潮和低潮的数值。(Least squares method returns tide level, tidal according dooson return number, and calculate the harmonic constants, values ​ ​ more than the water level, high tide and low tide.)

主要用于三次样条拟合，对离散点进行拟合插值，(Three order spline fitting)

可以对高温状态下的混凝土材料进行准确的塑型模型构建(It can be used to construct accurate plastic model of concrete under high temperature)

说明：  共轭梯度法求解线性方程组,主要采用FR共轭梯度法(solve liner solutions from CG)

用C++编的一些最优化作业中的程序,有Newton法,DFP法,共轭梯度法,单纯形法,内点法,外点法,内外点法,都能使用,我已经全部调试过了(C compile some of the most optimized operating procedures, Newton, DFP, conjugate gradient method, the simplex method, interior point method, the points outside the law, outside point method can use, I have all over Debugging)

用多重网格方法求解泊松方程，偏微分方程求解(use multigrid method to solve poisson equation, pde solver)

Maximum Flow Graph (Boykov Kolmogorov Algorithm)

美国汪利宏的蒙特卡洛及卷积模拟程序，可以模拟top-hat光束和高斯光束在生物组织中的传输(U.S. WANG Li-hong of the Monte Carlo and convolution simulation program can simulate the top-hat beam and Gaussian beam transport in tissue)

最小二乘法含有非线性线性拟合附有理论和实际的例子说明比较具有实际应用哟(PLS)

这是一个三次样条插值函数实现的C代码。如果插值点需要改变，可以在程序中改定。(This is a cubic spline interpolation function of the realization of the C code. If interpolation points need to change, the procedures will change.)
