Alternative proofs of theWeierstrass uniformapproximation theorem
have been provided by numerous mathematicians, including
renowned ones. Among them, there was Bernstein that used
a set of polynomials known as the Bernstein polynomials. Motivated
by the advancements in computational disciplines,we propose
a new type of Szász-Mirakjan-Kantorovich operators that
incorporate a shape parameter α. Certain shape-preserving properties,
such as monotonicity and convexity, are achieved by computing
the first and second order derivatives of the proposed
operators. Certain approximation properties, including the statistical
rate of convergence, are also obtained using a regular
summability matrix. Finally, theoretical results are supported by
illustrative graphics and numerical experiments using the Mathematica
computer program. The operators defined in this paper
may be used in computer and computational sciences, including
in robotic manipulator control.
