scipy.interpolate.interp2d¶
- class scipy.interpolate.interp2d(x, y, z, kind='linear', copy=True, bounds_error=False, fill_value=nan)¶
Interpolate over a 2D grid.
Parameters : x, y : 1D arrays
Arrays defining the coordinates of a 2D grid. If the points lie on a regular grid, x can specify the column coordinates and y the row coordinates, for example:
x = [0,1,2]; y = [0,3,7]
otherwise x and y must specify the full coordinates, for example:
x = [0,1,2,0,1,2,0,1,2]; y = [0,0,0,3,3,3,7,7,7]
If x and y are multi-dimensional, they are flattened before use.
z : 1D array
The values of the interpolated function on the grid points. If z is a multi-dimensional array, it is flattened before use.
kind : {‘linear’, ‘cubic’, ‘quintic’}
The kind of interpolation to use.
copy : bool
If True, then data is copied, otherwise only a reference is held.
bounds_error : bool
If True, when interpolated values are requested outside of the domain of the input data, an error is raised. If False, then fill_value is used.
fill_value : number
If provided, the value to use for points outside of the interpolation domain. Defaults to NaN.
Raises : ValueError when inputs are invalid. :
