I guess that with "complexes" you mean non-real number. After all 5 is a real number and as such its a complex number, too 😉

Not sure what exactly you have in mind if you write the you want to "find" those non-real numbers.

Here are a few suggestions - hope it helps:

Remarks:

"match" will fail if no non-real number is included in the vector

"trim" will fail if all vector elements are non-real

A workaround is to create modified "match" and "trim" functions:

Note: In Prime use "else" instead of "otherwise" and "try" instead of "on error"
