Top right panel: The fractional derivatives of the linear B-spline $B_0$ for $\gamma = 0.00, 0.0, 0.00$. Bottom left panel: The fractional derivatives of the cubic B-spline $B_0$ for $\gamma$ ranging from 0.00 to 0. Bottom right panel: The fractional derivatives of the fractional B-spline $B_{0.0}$ for the $\gamma$ ranging from 0.00 to 0. Ordinary derivatives are displayed as dashed lines.
