[It is the policy of this newsgroup and mailing list to not discuss non-Mathematica systems, but since the ToMatlab package is provided on the Wolfram Research site, I am permitting it this time. - Moderator] Hello, I've stumbled across the ToMatlab package to extract some long equations derived in Mathematica to be used in an embedded controller via Matlab. It appeared to be the answer to all my problems, but I'm afraid it wasn't quite so handy as I initially thought. Two questions to try and salvage the situation; sorry for my ignorance -- I'm a very new Mathematica user. I've got a bunch of subscripted variables and I want to transform them into, well, "not subscripted" variables. For example, Subscript[x_, y_] -> xy. I'm embarrassed that even this simple task I can't complete. Obviously the variable "xy" doesn't match the x_ and y_, so I need instead a round-about way to get a concatentation of the two. Secondly, I've also got a bunch of Greek variables. Is there an automatic way (that is, without enumerating them all in a ReplaceAll[]) to swap out the unicode character with their "name"? E.g., {\[alpha] -> alpha} for all the greek letters and variant greek letters? (Oh how I wish Matlab would accept unicode characters for variable names.) Many thanks in advance, Will Robertson
