DiracComb

DiracComb[x]
represents the Dirac comb function giving a delta function at every integer point.
DiracComb[x1, x2, ...]
represents the multidimensional Dirac comb function.
  • DiracComb can be used in derivatives, integrals, integral transforms and differential equations.
DiracComb vanishes for non-integer arguments:
DiracComb stays unevaluated for integer x:
The Fourier transform of DiracComb is a DiracComb:
