Applies B-spline interpolation to input control points (knots).


In the following, A1 to An, and B1 to Bk are optional batch dimensions.

knots A tensor with shape [B1, ..., Bk, C] containing knot values, where C is the number of knots.
positions Tensor with shape [A1, .. An]. Positions must be between [0, C - D) for non-cyclical and [0, C) for cyclical splines, where C is the number of knots and D is the spline degree.
degree An int between 0 and 4, or an enumerated constant from the Degree class, which is the degree of the splines.
cyclical A bool, whether the splines are cyclical.
name A name for this op. Defaults to "bspline_interpolate".

A tensor of shape [A1, ... An, B1, ..., Bk], which is the result of spline interpolation.
