// A 1-dimensional unary hat.

// <synopsis>
// A <src>Unary</src> is described by a height, a center and a width
// (halfwidth). The value is:
// <srcblock>
// height (|x-center| < width)
// 0.5height (|x-center| == width)
// 0 (|x-center| > width)
// </srcblock>
// The parameters are enumerated by HEIGHT, CENTER and WIDTH. They have
// default values of (1, 0, 1).
// </synopsis>
//
// <example>
// <srcblock>
// UnaryFunction<Double> sf(5.0, 25.0, 7);
// sf(25); // = 5.0
// </srcblock>
// </example>
// <templating arg=T>
// <li> T should have standard numerical operators
// </templating>
// <thrown>
// <li> AipsError if incorrect parameter number specified.
// </thrown>
