问题
I know that we can produce a single subscript in matplotlib like
$r_i
will give me an r with "i" as the subscript.
But I want to generate a subscript with say 3 or 4 letters, like r_ijk should give me an r with "ijk" as the subscript.
When I do the above, I only get the first ("i") to be the subscript, the rest ("j" & "k") are becoming normal scripts.

I just tried r_{ijk} and it did the trick! I was previously trying with () braces.
