- scipy.interpolate.pchip_interpolate(xi, yi, x, der=0, axis=0)¶
Convenience function for pchip interpolation.
See PchipInterpolator for details.
xi : array_like
A sorted list of x-coordinates, of length N.
yi : list of lists
yi[i] is the list of derivatives known at xi[i]. Of length N.
x : scalar or array_like
Of length M.
der : integer or list
How many derivatives to extract; None for all potentially nonzero derivatives (that is a number equal to the number of points), or a list of derivatives to extract. This number includes the function value as 0th derivative.
axis : int, optional
Axis in the yi array corresponding to the x-coordinate values.
y : scalar or array_like
The result, of length R or length M or M by R,
