A 1-dimensional sinc function.

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).

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

Constructs the SincFunction, Defaults: height=1, center=0, width=1.

Could not use default arguments that worked both with gcc and IRIX

Destructor

Evaluate the Sinc at x. If a vector is used as the argument only its first element is used.

Return a copy of this object from the heap. The caller is responsible for deleting this pointer.
