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 fitti

程序的二元一次方程拟合是针对遥感数据逐像元拟合的。最终会输出各自变量系数以及常数项(以图像形式输出)(The binary first-order equation fitting of the program is pixel-by-pixel fitting for remote sensing data. Ultimately, the coefficients of each variable and the constant terms (output in image form) a
