| Abstract: | In this paper, a kind of generalized one-dimensional and two-dimensional Stancu operators are constructed,and the sufficient and necessary conditions for uniform convergence by these operators in the space C is studied. By using the modulus of smoothness, the rate of convergence of these operators is estimated. |
