This is a simple one-dimensional test function. Currin, C., Mitchell, T., Morris, M., & Ylvisaker, D. (1988). A Bayesian approach to the design and analysis of ...

An evaluation of the derivative of spherical Bessel functions of order n + 1/2 at its zeros is obtained. Consequently, an explicit quadrature formula for entire functions of exponential type is given.
