This example illustrates some properties of splines. Splines are curves, which are usually required to be continuous and smooth. Splines are usually defined as piecewise polynomials of degree n with ...

This example then specifies a smoothed spline interpolation method on the GRID statement. As shown by the following output, the resulting surface plot is smoother still. libname reflib ...

The ubiquitous ball spline. Basically, it is a type of mechanical element used in a variety of industrial applications where precise movement and alignment is required, like machine tools, robot arms ...

Ball splines and bearings: each play a role in mechanical function, and each are unique. All types of machinery are provided with supports for rotating shafts, and that supporting device is a ...
