| Abstract: | Cubic quasi-Ferguson curve was constructed through the extension of cubic Ferguson curve. The shape of the curve could be adjusted by changing the values of the shape parameter A. The new curve has the cubic Ferguson curve as its special case and possesses the main properties of cubic Ferguson curve. Boundary conditions of the cubic quasi-Ferguson curve and the conversion matrix between the curve and several kinds of spline era＇yes with shape parameter are also presented. |
