scipy.interpolate.spleval¶

scipy.interpolate.
spleval
(*args, **kwds)[source]¶ spleval
is deprecated! spleval is deprecated in scipy 0.19.0, use BSpline instead.Evaluate a fixed spline represented by the given tuple at the new xvalues
The xj values are the interior knot points. The approximation region is xj[0] 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.
Parameters: (xj, cvals, k) : tuple
Parameters that define the fixed spline
 xj : array_like
Interior knot points
 cvals : array_like
Curvature
 k : int
Order of the spline
 xnew : array_like
Locations to calculate spline
 deriv : int
Deriv
Returns: spleval : ndarray
If cvals represents more than one curve (cvals.ndim > 1) and/or xnew is Nd, then the result is xnew.shape + cvals.shape[1:] providing the interpolation of multiple curves.
Notes
Internally, an additional k1 knot points are added on either side of the spline.
