matlab曲面拟合强烈向做实验数据处理的朋友推荐，该函数特别适合空间点的曲面拟合，matlab中对于此类数据点似乎只能用griddata差值计算，并且效果不怎么好；至于B样条拟合，其外扩数据点的选取不是一般的matlab用户所能掌握的，同时对于非网格数据的转换也是一个问题。。。(matlab surface fitting is strongly recommended to friends experiment data processing, the function surface fitting particularly suitable space point the matlab for such data points seems calculated only use griddata difference, and the effect is not very good As for the B-spline Article fitting the outer expanding selection of data points is not an ordinary the matlab user can master, while for non-grid data conversion is also a problem. . .)
