There days, I try to learn cadabra to help me to do computation, it is great and I like it. BUT I find there are some things could be done better :
If cadabra could implement substitute operation continuously like mathematica in following method
, cadabra will be easier to use. After all, most people use this function frequently;
Add code completion;
Add usage of keyboard shortcuts;
Add functions trace(especially,for gamma matrix) and dagger( I have mentioned it at another place);
substitute or add a function can change
a b ... c d.. to
c d...a b... ;
Update this paper Tutorial and reference guide to 2.x;
Add optional parameter to make
function keep original value unchangable after implementing(especially, function
Make notebook supports Chinese language when writing in latex mode.
I just wish cadabra would be more perfect.Thanks for your so great work again.
