__call__(x, nu=0, extrapolate=None)¶
Evaluate a spline function.
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.
y : array_like
Shape is determined by replacing the interpolation axis in the coefficient array with the shape of x.
