splevalis deprecated! spleval is deprecated in scipy 0.19.0, use BSpline instead.
Evaluate a fixed spline represented by the given tuple at the new x-values
The xj values are the interior knot points. The approximation region is xj to xj[-1]. If N+1 is the length of xj, then cvals should have length N+k where k is the order of the spline.
- (xj, cvals, k) : tuple
Parameters that define the fixed spline
- xj : array_like
Interior knot points
- cvals : array_like
- k : int
Order of the spline
- xnew : array_like
Locations to calculate spline
- deriv : int
- spleval : ndarray
If cvals represents more than one curve (cvals.ndim > 1) and/or xnew is N-d, then the result is xnew.shape + cvals.shape[1:] providing the interpolation of multiple curves.
Internally, an additional k-1 knot points are added on either side of the spline.
