Details

  • This message is generated when the "DoubleExponentialOscillatory" method gives a finite numerical result for a possible divergent integral. In that case the numerical computation of should be understood as
  • Off[message] switches off the message; On[message] switches it on. For example: Off[NIntegrate::deodiv].

Examples

Basic Examples  (1)

This example shows a divergent integral for which "DoubleExponentialOscillatory" gives a finite result:

Wolfram Language code: NIntegrate[Sin[x], {x, 0, ∞}, Method -> "DoubleExponentialOscillatory"]

The numerical integration above corresponds to the following symbolic computation with Integrate and Limit:

Wolfram Language code: Limit[Integrate[Exp[-c x]Sin[x], {x, 0, ∞}], c -> 0]
