根据已知的三维离散数据（x,y,z）,在MATLAB中利用此函数进行三维曲面拟合，再根据polyval2d得出拟合函数的系数矩阵。(according to 3D discrete datum (x,y,z),use this function in MATLAB to fit 3D surface, and use polyval2d to get coefficient matrix)

I created a script that show how to remove repeatable noise with standard pattern in an image.

什么也不用说了，MIT的MATLAB教程，最好的学习资料，最实用的分析工具(Needless to say nothing, MIT' s MATLAB tutorial, the best learning materials, the most useful analytical tools)

说明：  matlab实现最优化选择的一个算法，大家可以下下来参考，我也是从别处down的，谢谢原作者(matlab optimize the choice of an algorithm, we can refer to the next down, I am also down elsewhere, thank you, original author)
