Only for those that were actually present or for any of them? In the second case, you can simply add cc[__] = 0.

| Feb 3 at 18:53 | comment | added | QFTheorist | Thanks. @Domen would it be possible to keep the values of the terms that I have set to 0 too? i.e. something like cc[a,b,c] = 0. | |

Sure! If you simply write cc@@c[2,0,0] = ... which is equivalent to Apply[cc, c[2, 0, 0]] = ..., Mathematica will complain that you are trying to assign some value to the Apply! This is because Set has the attribute HoldFirst. To overcome this, we use Evaluate such that cc@@c[2,0,0] is evaluated first to cc[2,0,0], and only then Set is called to set the value.

Hi @Domen , thanks for the solution. It works as I would like it to. Can you explain what the Evaluate[cc@@#1]... bit is doing exactly? I have seen apply and map before but this is new. Thanks.
