- BSpline.__call__(x, nu=0, extrapolate=None)[source]#
Evaluate a spline function.
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.
Shape is determined by replacing the interpolation axis in the coefficient array with the shape of x.
