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.
WebThe RBF interpolant is written as. f ( x) = K ( x, y) a + P ( x) b, where K ( x, y) is a matrix of RBFs with centers at y evaluated at the points x, and P ( x) is a matrix of monomials, … WebIn the plots above, the RBF interpolant is quite good, but if one chooses a shape parameter poorly this will not be the case. In the image below we see an example where the shape parameter is chosen to be $\varepsilon = 10^4$ and, though it interpolates, it is a terrible approximation to the function.
