It seems I can't put incomplete gamma functions into user defined functions.
While they are correctly calculated if assigned to a variable or directly inputted,
They give an odd error with "- not defined" when they are in a function.

Hi overlord. Try this please, which prevent the error evaluating the function definition.



Best regards.
Alvaro.

It works indeed, thank you Alvaro.
I would never thought a line could get around this error.
But why even this error exists? And can it be fixed?
