Function-wise differentiation code? #41
Description
Hello, I was reading your paper and was trying to find an example of how the "function-wise differentiation" works. I went through your code but couldn’t find anything related. Could you please point me to where it is implemented, if it is included?
On the other hand, I'm wondering how it is faster than pointwise differentiation. Though the expression seems to be more efficient, eventually the function-wise one would require to calculate the pointwise grad.
