I sometimes don't understand why people close questions even when there are valid reasons given for not closing it. Look at this specific question. The last comment on the question explains why the question should remain. Even after reading that, I can see that question was closed. I find the question general and a question which deserves some effort, and that is why deserves to be on the forum. It is neither too specific nor something which everybody will know. I want to know whether this question can be opened.
Also, I am just quoting a comment on the question here as I know there are many more questions with the similar title.
As the closure message states, this is off-topic. It is not a practical programming problem that you face. i.e. there is no code involved.
The question which I am referring to also has no code, but it is not necessary that every question should have code, right?
P.S. I am not the author of the question but I know a few things about MATLAB and I am really curious why moderators feel that this question is not upto the "standards". This is a genuine question from me and I hope to get some answer though I know that such questions are usually closed.
