中文说明：
径向基函数插值使用一系列基函数，它们在每个采样点对称且居中。径向基函数是一类特殊的函数，其主要特征是它们的响应与中心点的距离单调地减小（或增加）。中心、距离刻度和精确的形状是模型的参数。
English Description：
Radial basis function interpolation uses a series of basis functions, which are symmetrical and centered at each sampling point. Radial basis functions are a special kind of functions whose main characteristic is that the distance between their response and the center point monotonically decreases (or increases). Center, distance scale and precise shape are the parameters of the model
