In this paper a rational cubic function in the form of cubic/quadratic, with three shape parameters has been developed. Data dependent sufficient constraints are derived for one of these shape parameter to preserve the shape of constrained data that is lying above the straight line. Remaining two of these shape parameters are left free for designer’s choice… (More)
