comment Explanation for coloring of variables by code editor?
@KeeganMcCarthy Are you using a notebook specific context or is this all in Global? If the former, then this is not unusual.

OP had a response to you in a deleted answer (which is now an addendum to the question). Please respond under the question to notify them (if you choose to respond).

comment Calendar view outline
@alancalvitti Sorry, I've lost access to Mathematica and until I get around to buying a copy, I won't be able to answer. I believe you just need the definition of boundary for my answer and this part is in the question.

I believe you can use this answer of mine to get the outline as a closed Line (just feed the points to Line).

comment My Baum-Welch algorithm is very slow. Is it due to Mathematica?
(Just so you know, some of these comments are automatically generated from the /review queue). To commenters and flaggers: the "commentness" of the answer is noted and I think we all (including Igor) agree on that. However, Igor also has a valid point that the link does answer the question fully and reproducing the code there (which is a lot) is kinda futile. Please participate in the meta discussion if you have thoughts/more to say on this. I will not be deleting this answer.

comment My Baum-Welch algorithm is very slow. Is it due to Mathematica?
That is a lot of code for anyone on this site to have time to read/critique/analyze it fully and most likely, no one is going to. However from a quick glance at the code, I can most certainly say that the slowness is due to the procedural programming style. All those Sum[Sum[Sum[Sum... terms in nested Whiles are bound to give terrible performance. Writing the algorithm in a functional manner would certainly speed things up a lot. Unfortunately, it is hard (for me at least) to recommend specific changes to make to your code. If I were you, I'd start afresh with functional (use Igor's link)

comment Is garbage collection broken in version 10.0.0?
I don't have 10.0.1 or Mathematica with me now, but what you're describing doesn't seem unexpected. I think if you re-evaluate the top cell a second time, you should see {"foo$"} in the output.

comment How do I plot the images of oriented curves under complex transformation?
I used to have a "systematic way to obtain a nice parametrization of an arbitrary conic" — it was called "Ask J. M." :)

comment How do I bandpass a signal in Mathematica 8
@Mr.Wizard No, sorry. It's a lot of time commitment and detail that's well beyond the scope of this site. OP still hasn't replied to my question re: MATLAB. If that's the case, then the second example here would be the best way to proceed.
