Etymology

A 1-dimensional sinc function.

Synopsis

A Sinc is described by a height, a center and a width (halfwidth). The value is:

         let y = (x-center)/width
         height                              (x == center)
         height*sin(pi*y)/(pi*y)             (x |= center)

The parameters are enumerated by HEIGHT, CENTER and WIDTH. They have default values of (1, 0, 1).

Example

       SincFunction<Double> sf(5.0, 25.0, 7);
       sf(25);            // = 5.0
