However, the generalized moving least squares approximation makes require least squares approximation with regard to functional and its derivative value on all nodes.
而广义移动最小二乘近似要求近似函数及其导数在所有节点处的误差的平方和最小。
3
The paper probes into the relation between functional differentiability and the derivative function limit, and the relation between asymptote of function and the derivative function limit.
