Absolute value of real[int,int]

In the FreeFEM manual it is said that the function abs() should work on arrays of type real[int,int]. In practice, when I try to use it I get the error: Warning ambiguity Polymorphic Find 2. I have FreeFem 4.6 installed.

Is this the normal behavior? What is the proper way to compute the absolute value of every item of an array without looping?

Thank you, Beniamin

Hi Beniamin, I tried and get the same ambiguity error. I tried other functions e.g.
sin(), cos() and they work but abs() not working. Probably a bug or a feature to be implemented…
