ApproxOp: A Unified Framework for Positive Linear Approximation Operators

Provides a unified computational framework for defining, evaluating, analyzing, comparing, and visualizing positive linear approximation operators. The package supports classical and generalized discrete operators, ordinary and central moments, numerical moment verification, approximation error analysis, convergence studies, parameter studies, and user-defined operators. The implemented framework is related to classical and generalized approximation operators described in Szász (1950) <doi:10.6028/JRES.045.024>, Sucu and Varma (2015) <doi:10.1016/j.amc.2015.08.077>, and Aliaga and Aslan (2026) <doi:10.1002/mma.70924>.
