Version 12.1 on a Mac
The question about the derivative of Abs'
has been asked several times, but all previous posts dealt with Abs'[x]
and my question is about Abs'[1]
.
It seems to me that there are no complex-numbers issues with Abs'[1]
, yet
Abs'[1]//N
does not simplify to 1.0. Is there a way to overcome this?
Edit:
For me, Abs
appeared as a result of calling Norm
on a real vector. How do I make it use RealAbs
?
