scipy.interpolate.BSpline.
__call__#
- BSpline.__call__(x, nu=0, extrapolate=None)[source]#
 Evaluate a spline function.
- Parameters:
 - xarray_like
 points to evaluate the spline at.
- nuint, optional
 derivative to evaluate (default is 0).
- extrapolatebool 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:
 - yarray_like
 Shape is determined by replacing the interpolation axis in the coefficient array with the shape of x.
