In [8] the existence and uniqueness problem of solution in periodic quartic polynomial spline histopolation (m = 4) is stated generally but solved only for the uniform grid.

Periodic polynomial spline histopolation

Following [14] for a Quartic polynomial, P(x) = [a.sub.0] + [a.sub.1] x + [a.sub.2] [x.sup.2] + [a.sub.3] [x.sup.3] + [a.sub.4][x.sup.4].

A ROM-less direct digital frequency synthesizer based on hybrid polynomial approximation

Since the larger values of [R.sup.2] and [R.sup.2.sub.adj] and the smaller values of RE and RMSE indicate a better fitness of the RS models, it is found that compared to other response functions the quartic polynomial functions provide the best approximation on the column's responses and therefore should be used for optimum design.
