该函数用于二维曲面拟合，能拟合出f=（x，y）的函数图形。-Gridfit is a surface modeling tool, fitting a surface of the form z(x,y) to scattered (or regular) data. As it is not an interpolant, it allows the existence of replicates in your data with no problems.

此程序主要是用Matlab进行点云数据的三维建模，对用Matlab进行三维重建有实用价值。 -The procedure is to use Matlab for modeling three-dimensional point cloud data on the three-dimensional reconstruction with Matlab has practical value.

这是一个非常有用的程序，能够用来对已有的数据进行拟合，便于图形显示。(this program can be used to Interpolate, and smooth, add data points,Graphics display, matlab drawing.)
