Numerical Integration Based on Bivariate Quartic Quasi-Interpolation Operators
《Numerical Mathematics A Journal of Chinese Universities(English Series)》2007年第3期226-232,共7页Renhong Wang Xiaolei Zhang 
This project was supported by the National Natural Science Foundation of China (No. 60373093, No. 60533060).
In this paper,we propose a method to deal with numerical integral by using two kinds of C^2 quasi-interpolation operators on the bivariate spline space,and also dis- cuss the convergence properties and error estimates...
