Dirac delta function in simple words
WebJul 25, 2015 · Dirac's $\delta$ is a distribution, not a function per se. Formally $\langle\delta,f\rangle=f(0)$. A common choice for the space where these things live is … WebThe delta function is a generalized function that can be defined as the limit of a class of delta sequences. The delta function is sometimes called "Dirac's delta function" or the "impulse symbol" (Bracewell 1999). It is implemented in the Wolfram Language as DiracDelta[x]. Formally, delta is a linear functional from a space (commonly taken as a …

The concept of a function as being a mapping from one set to another set is (from our luxurious perspective of having hindsight) a completely standard concept. So, in this regard the dirac delta is simply a function/mapping.
