Replaces null values by interpolating the gaps based on calculated cubic splines and linearly extrapolating ... with the Value1Argument and Value2Argument is identical to the LINEAR_APPROX function ...

To solve the problem, this paper presents an algorithm for elementary function approximation in single-precision floating-point format, which is based on minimax piecewise cubic polynomial ...

Previously, Norman and co-workers had taken a similar approach to develop the linear and quadratic complex response functions. This new study is a continuation of that work with a focus on the cubic ...
