GRIDFIT是一个曲面建模工具，它的形式为z（x; y）分散（或定期）数据。 由于它不是插值，它允许在您的数据中存在重复，没有问题。 我的意思是什么由“插值”？ 插值是一个总是被设计的代码准确预测所有提供的数据。 GRIDDATA和INTERP1就是例子
插值。 GRIDFIT更准确地描述为近似值。它产生一个表面，表示所提供数据的行为
尽可能接近，允许数据中的噪声和复制数据。(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. What do I mean by an "interpolant"? An interpolant is a code that is designed to always exactly predict all supplied data. GRIDDATA and INTERP1 are examples of interpolants. GRIDFIT is more accurately described as an approximate. It produces a surface which represents the behavior of the supplied data as closely as possible, allowing for noise in the data and for replicate data.)
