Detailed Description
template<class T>
class casacore::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.
