NIntegrate::deoncon

Details

  • This message is generated when the final (fourth) attempt to compute the integral by the method "DoubleExponentialOscillatory" gives an error estimate that does not satisfy the precision goal.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[NIntegrate::deoncon].

Examples

Basic Examples  (1)

This shows an example of an integral for which "DoubleExponentialOscillatory" does not reach the precision goal:

Wolfram Language code: NIntegrate[Sin[18x]Cos[12x] / (x + 1), {x, 0, ∞}, Method -> {"DoubleExponentialOscillatory", "Method" -> None}]

Increasing the WorkingPrecision or the PrecisionGoal gives a more correct result:

Wolfram Language code: NIntegrate[Sin[18x]Cos[12x] / (x + 1), {x, 0, ∞}, Method -> {"DoubleExponentialOscillatory", "Method" -> None}, WorkingPrecision -> 20]
