I know that I can wrote something like $a_1 + \cdots + a_n$ without the dots as $\sum_{i=1}^n a_i$ which seems clearer to me. As a programmer, I'd rather have a rule set with variables than something with dots where I have to extract the pattern from.
Is there some notation to do this for the parameters of a function? Say a Lagrangian like so: $L\left(q_1, \ldots, q_n, \dot q_1, \ldots, \dot q_n, t\right)$
The thought in the back of my head is the following. In Python, I could have a function like so:
f(x, y, z)
When I call that function, I could either to f(1, 2, 3)
or I could do the following:
parameters = [1, 2, 3] f(*parameters)
Where I basically “dump” that list of parameters into the parenteses of the function. Is there some math notation for the same thing?
