Here, we use n piecewise cubic polynomials for interpolation, g(x) = gi(x), for xi ≤ x ≤ xi + 1. To achieve a smooth interpolation we impose that g(x) and its first and second derivatives are continuous. The requirement that g(x) is continuous (and goes through all n + 1 points) results in the two constraints.
