6h	comment	Does Mathematica have a command analogous to ode45 of MATLAB? This is nice, but is it a coupled second-order system? I think that would be more helpful to the original poster.
7h	comment	How to manipulate a plot with intermediate parameters Dear lcet, this is your fourth question posted on the site. People are generally finding them hard to follow. It is often not clear what you are wanting. That is one reason you are getting downvotes. The other is that you are dumping large amounts of hard-to-read code in your questions. Please simplify your code to a minimum working example, and use normal letters instead of greek letters for parameters.
1d	comment	how to create dynamic 2D table algorithm How does this question relate to the software Mathematica? I think you might be in the wrong place.
Jun 9	comment	A function that accepts a pair or a list of pairs Congratulations on hitting 10000 rep points !
Jun 4	comment	ListVectorPlot3D hi @Domi, please don't use answers to post clarifications to questions. I've moved your update into the question.
May 30	comment	How to use “for” to “show” a row of cuboids in a same coordinate? If the issue is that you want to have lots of little cuboids with different values of `iii` and `jjj`, just change the line defining `TT` to: `TT = Table[Cuboid[{0.4, 0, 0.1}, {0.6, 0.2, f[ii, jj]}], {ii, 0.1, 0.8, 0.1}, {jj, 0.2, 0.9, 0.1}];`. You can include this in `Show` as normal. `Table` is usually a better choice than `For` in Mathematica. You might find this Q&A helpful.
May 30	comment	How to use “for” to “show” a row of cuboids in a same coordinate? Welcome to Mathematica.SE, Bruce! I formatted your code for you. Please see the FAQ for information on how to do this. Also, your question is not clear. I get a graphic using this code. In what way do you have difficulty? Please note that using single-capital-letter names for things as considered bad practice as it can clash with built-in symbols.
May 23	comment	Having used Mathematica as a “gateway” language, where to from here? I don't want to close this question, but I would ask that people posting answers address some key issues that would be relevant to Mathematica users: (1) integration with Mathematica; (2) learning curve for someone already familiar with Mathematica and functional programming; (3) value-add of things Mathematica doesn't do so well (o/o, performance etc).
May 20	comment	Setting OperatorSubstitution to False has issues with PDF and EPS exports. Are these bugs? Could this be an issue with the font? I can't replicate the PDF export problem on Windows using Verdana, Consolas or Vivaldi: it definitely uses the selected font for operators and the custom Mathematica fonts are not used. And I have never had this problem on my Mac at home. I have Mathematica 9 on both machines. Maybe try Consolas for the time being?
May 20	comment	from complex function to a series After tidying up your expression and using `FullSimplify` on it, I get zero. Is that what you expected?
May 15	comment	How do I operate on a set of ordered pairs? `Plus @@@ (data^2)`. `Power` is `Listable`.
May 2	comment	Predictive code completion and custom functions in contexts @wolfies - I just checked, and after implementing halirutan's solution, yes, both (a) and (b) work for my custom functions. Well, I get a "file not found" error when I try to open documentation pages that don't exist, but it works other than that :)
May 2	comment	Predictive code completion and custom functions in contexts @wolfies I can't answer this as I haven't yet written the function help pages.
Apr 29	comment	SetPrecision with indexed variables @DanielLichtblau - please post this as an answer
Apr 20	comment	How can I fix Mathematica's text line-breaking algorithm not to line-break so soon? @RolfMertig - unfortunately adding LaTeX into this system is not going to fly with the users. I just want to wrap text in a text box the way any other program would do.
Apr 19	comment	Interactively Manipulate Code Create a Dynamic variable that is the `Head` of an expression, and can take the values `Plus` or `Times`
Apr 19	comment	How can I fix Mathematica's text line-breaking algorithm not to line-break so soon? Thanks - I had tried some very high numbers but perhaps hadn't been comprehensive enough. The documented numbers are all pretty low. Is this algorithm based on the one in TeX? If so, that would be worth including in your answer.
Apr 17	comment	build and estimate a time series process @PlatoManiac I'll try to get to it tonight.
Apr 17	comment	build and estimate a time series process To be fair, that notebook on Verbeia.com is very old - probably version 4 vintage. @PlatoManiac - how come you remember what is on my web site better than I do?
Apr 9	comment	StreamPlot in Polar Coordinates Thanks Andre, although the other one was posted first, I've marked it as the duplicate and this one as the canonical version.
