Interp1 x y xi spline

WebThe reader should note that the Matlab function interp1 can also be used to fit splines to data. The call interp1(x,y,xi,'spline') is identical to spline(x,y,xi). A special type of spline is the Bézier curve. This is a cubic function defined by four points. The two end points are used, together with two 'control' points.
