Hi, I am using Mathematica 12.3 and the FeynCalc version is 9.3.1. I have a tensor, using which I want to write a symmetrized version of it. e.g. - if I have, f(x,y), upon symmetrization, I would like to have, f(x,y) + f(y,x). I found the function 'Symmetrize' for this purpose as described in https://www.feyncalc.org/FeynCalcBook/Symmetrize/index.html But when using it on my computer, it doesn't work. I get the following: In[1] Symmetrize[f[a, b], {a, b}] whereas I expected : I don't understand this function 'Symmetrize' works. The Mathematica database does not mention anything like the above website. Has the functionality of 'Symmetrize' as mentioned in the above website changed? Is there a way out to achieve what I am looking for? |

Hi, that documentation page is completely outdated. You should use https://feyncalc.github.io/reference for the stable version and https://feyncalc.github.io/referenceDev for the dev version The function has been renamed to https://feyncalc.github.io/FeynCalcBook/ref/FCSymmetrize.html |
