Hi all,
I have a question which seems trivial but simply cannot figure out its
solution.
I want to type A_{\alpha,\beta} in the title of a plot. Uwe once pointed
out a solution
expression(A[alpha*beta])
But the output of the above command does not include the "," in the
subscript. Is there a way to solve my question? Thanks so much!
Regards,
Jeff
