represents the Heaviside theta function , equal to 0 for and 1 for .
represents the multidimensional Heaviside theta function, which is 1 only if none of the xi are not positive.
- HeavisideTheta[x] returns 0 or 1 for all real numeric x other than 0.
- HeavisideTheta can be used in integrals, integral transforms, and differential equations.
- HeavisideTheta has attribute Orderless.
- For exact numeric quantities, HeavisideTheta internally uses numerical approximations to establish its result. This process can be affected by the setting of the global variable $MaxExtraPrecision.
