DiracDelta

DiracDelta[x]
represents the Dirac delta function .

DiracDelta[x1,x2,]
represents the multidimensional Dirac delta function .

DetailsDetails

  • DiracDelta[x] returns for all numeric x other than .
  • DiracDelta can be used in integrals, integral transforms, and differential equations.
  • Some transformations are done automatically when DiracDelta appears in a product of terms.
  • DiracDelta[x1,x2,] returns if any of the are numeric and not .
  • DiracDelta has attribute Orderless.
  • For exact numeric quantities, DiracDelta internally uses numerical approximations to establish its result. This process can be affected by the setting of the global variable $MaxExtraPrecision.
