We use a statistical convergence type and power series method to obtain certain Korovkin type theorems, and we study certain rates of convergences related to these summability methods. Furthermore, we numerically analyze the theoretical results and provide some computer graphics to emphasize the importance of this study.enfour dimensional matrixdouble sequencepower series methodstatistical convergencecomputer graphicserror of approximationArticle
