Detailed Description

template<class T>
class casa::DiracDParam< T >

A one dimensional Dirac delta function.

Intended use:

Internal

Review Status

Test programs:

tFunctionHolder

Prerequisite

• FunctionParam class
• Function class

Etymology

A 1-dimensional Dirac delta.

Synopsis

A DiracD is described by a height and a center The value is:

         height          (|x-center| == 0.0)
         0               (|x-center| != 0.0)

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

Example

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

Template Type Argument Requirements (T)

• T should have standard numerical operators

Thrown Exceptions

• AipsError if incorrect parameter number specified.
