class scipy.interpolate.interp2d(x, y, z, kind='linear', copy=True, bounds_error=False, fill_value=None) [source] ¶ Interpolate over a 2-D grid. x, y and z are arrays of values used to approximate some function f: z = f (x, y). This class returns a function whose call method uses spline interpolation to find the value of new points.

SciPy provides us with a module called scipy.interpolate which has many functions to deal with interpolation: 1D Interpolation The function interp1d() is used to interpolate a distribution with 1 variable. 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. The scipy.interpolate packages wraps the netlib FITPACK routines (Dierckx) for calculating smoothing splines for various kinds of data and geometries.

This class returns a function whose call method uses spline interpolation to find the value of new points. SciPy provides us with a module called scipy.interpolate which has many functions to deal with interpolation: 1D Interpolation The function interp1d () is used to interpolate a distribution with 1 variable. It takes x and y points and returns a callable function that can be called with new x and returns corresponding y. The scipy.interpolate.Rbf is used for interpolating scattered data in n-dimensions.

The scipy.interpolate.Rbf is used for interpolating scattered data in n-dimensions. The radial basis function is defined as corresponding to a fixed reference data point. The scipy.interpolate.Rbf is a class for radial basis function interpolation of functions from N-D scattered data to an M-D domain. Syntax: scipy.interpolate.Rbf(*args)
