摘要
建立了一般节点情形下的一类广义差商,推导出了这类广义差商的性质,从而推广了差商的概念,在此基础上,利用广义差商构造函数插值,简化B样条基函数表示。
A new kind of generalized difference quotient with any base point has been defined. The properties of generalized difference quotient have been discussed.Futhermore, some examples of applications, such as interpolation function B-spline curve function are given.
