摘要：

In the present article we find direct quantitative estimate for approximation of complex valued functions by linear combinations of the complex Phillips operators. Here we extend the recent results of Gal and Gupta (Mathematics without boundaries; Surveys in Interdisciplinary Research, 2014). We have been able to achieve the better approximation for the complex Phillips operators.
