Abstract:
The article considers the approximation of elongated spheroidal functions by finite series and proposes a method for calculating the coefficients of such series. The paper provides a numerical performance analysis of the invariance property of elongated spheroidal zero-order functions in relation to an integral transformation with a sinc-kernel on a symmetric bounded interval.
