Detailed Description

template<class T>
class casa::UnaryParam< T >

Parameter handling for one dimensional unary function.

Intended use:

Internal

Review Status

Test programs:

tFunctionHolder

Prerequisite

• FunctionParam class
• Function class

Etymology

A 1-dimensional unary hat.

Synopsis

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

         height          (|x-center| <  width)
      0.5height          (|x-center| == width)
         0               (|x-center| >  width)

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

Example

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

Template Type Argument Requirements (T)

• T should have standard numerical operators

Thrown Exceptions

• AipsError if incorrect parameter number specified.
