DeltaFunction¶

Description¶

DeltaFunction represets the Dirac delta function and can only be used with the Convolution:

$\int\limits_{A}^{B}R(x-\xi) \times \mbox{Height}\times \delta(\xi-\mbox{Centre}) \mbox{d}\xi = \mbox{Height} \times R(x-\mbox{Centre})$

Usually it is used as a part of a CompositeFunction, for example:

composite=Convolution; name=Resolution,Filename="Resolution.dat"; (name=DeltaFunction,Height=0.01; name=Lorentzian,Height=1,FWHM=0.1)

Name	Default	Description
Height	1.0	Scaling factor to be applied to the resolution.
Centre	0.0	Shift along the x-axis to be applied to the resolution.
