scipy.interpolate.BivariateSpline.ev

BivariateSpline.ev(xi, yi, dx=0, dy=0)[source]

Evaluate the spline at points

Returns the interpolated value at (xi[i], yi[i]), i=0,...,len(xi)-1.

Parameters:

xi, yi : array-like

Input coordinates. Standard Numpy broadcasting is obeyed.

dx : int

Order of x-derivative

New in version 0.14.0.

dy : int

Order of y-derivative

New in version 0.14.0.
