Union::smtst Intersection::smtst Complement::smtst

Details

  • This message is generated when the result of applying the value of the SameTest option to a pair of elements is not True or False.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[Union::smtst].

Examples

Basic Examples  (1)

A warning message is generated because a required inequality with an empty list does not evaluate to True or False:

Wolfram Language code: Union[{11, 3, 8, {}, 4, 7, 12}, SameTest -> (Abs[#1 - #2] < 2&)]

This value for the SameTest option is adequate if all of the elements are integers:

Wolfram Language code: Union[{11, 3, 8, 2, 4, 7, 12}, SameTest -> (Abs[#1 - #2] < 2&)]
