Davidon's cubic interpolation method
WebMay 16, 2024 · SciPy only has a built-in method to find the roots of a cubic spline. So there are two approaches: Use a 4th degree spline for interpolation, so that the roots of its derivative can be found easily. Use a cubic spline (which is often preferable), and write a custom function for the roots of its derivative. I describe both solutions below. WebThe divided differences method can be reused here, with repeating values of the x_i interpolation points. A repeated x_i gives an undefined divided difference, but the limit as interpolation points coalesce is well-defined as a derivative of f as long as f is smooth enough at that point. Natural cubic splines

Most of the methods are passed off to scipy.interpolate.interp1d; however for a few others there's a dict or other wrapper methods pointing to those specific scipy methods.
WebIn mathematics, bicubic interpolation is an extension of cubic spline interpolation (a method of applying cubic interpolation to a data set) for interpolating data points on a two-dimensional regular grid.The interpolated surface (meaning the kernel shape, not the image) is smoother than corresponding surfaces obtained by bilinear interpolation or nearest … WebINTER_AREA – resampling using pixel area relation.
