scipy.interpolate.BSpline.__call__

BSpline.__call__(x, nu=0, extrapolate=None)

Evaluate a spline function.

Parameters:

x : array_like

points to evaluate the spline at.

nu: int, optional

derivative to evaluate (default is 0).

extrapolate : bool or ‘periodic’, optional

whether to extrapolate based on the first and last intervals or return nans. If ‘periodic’, periodic extrapolation is used. Default is self.extrapolate.

Returns:

y : array_like

Shape is determined by replacing the interpolation axis in the coefficient array with the shape of x.
