WebSep 27, 2024 · 1-D interpolation ( interp1d) ¶. The interp1d class in scipy.interpolate is a convenient method to create a function based on fixed data points which can be evaluated anywhere within the domain defined by the given data using linear interpolation. An instance of this class is created by passing the 1-d vectors comprising the data. WebA multi-domained RBF interpolant is an RBF interpolant that has a number of individual sub-interpolants that are bounded by the fault blocks or output volumes of a selected geological model. Changes to all sub-interpolants can be made by editing the parent interpolant, while sub-interpolants can be edited to account for local influences on the values used, the …
