x values for interpolant
f(x) values for interpolant
uninitialized ndslice to write slopes into
uninitialized temporary ndslice
SplineType type of cubic spline.
tangent power parameter for cardinal SplineType (ignored by other spline types). Use 1 for zero derivatives at knots and 0 for Catmull–Rom spline.
left boundary condition
right boundary condition Constraints: points, values, and slopes, must have the same length > 3; temp must have length greater or equal to points less minus one.
Piecewise cubic hermite interpolating polynomial.
