JOURNAL OF COMPUTATIONAL AND APPLIED MATHEMATICS 2023年 第1期428卷
作者: Delgado, J. Orera, H. Pena, J. M. Univ Zaragoza Dept Matemat Aplicada IUMA Zaragoza Spain
An extension to triangular domains of the univariate q-Bernstein basis functions is introduced and analysed. Some recurrence relations and properties such as partition of unity and degree elevation are proved for them... 详细信息
