A perfect spline, often referred to in the context of spline interpolation or spline approximation, is a mathematical construct used to create a smooth curve that passes through a given set of points (or control points). In general, "spline" refers to a piecewise polynomial function that is defined on intervals, and a "perfect" spline typically implies that the spline fits the data points exactly without any error.
