Please see the end for my feature request - forcing users with [what would be] negative rep to have subsequent questions approved before they're viewable by the public.
As a fairly regular MATLAB asker/answerer on SO, I notice that there is a disproportionately high number of basic homework-help questions to legitimate MATLAB questions. What I mean is, a lot of questions might get asked that could be answered VERY quickly if one took the time to search (it's typically something immediately available in MATLAB documentation); is only tangentially related to MATLAB; or the asker has clearly made no attempt to solve the problem himself.
I want to apply Highpass filter to a image containing a line in matlab . So anyone can u help me out to designing a highpass filter in matlab and how to extract the frequency components in it
using some dataset example: data = [1,2,2,3,4]
how can I plot a normalised (0,1) smooth CDF (some call it s-shaped cdf) using matlab?
My function file starts with
function drawline(point1,point2,color,img), at the end, i'm supposed to return a image. How to code the return line. i post codes matlab:color issueThanks.
The function arithenco needs the input message to be a sequence of positive integers. Hence, I need convert a message into a sequence of numbers message_int, by using the following mapping: ‘A’→1, ‘C’→2, ‘G’→3, ‘T’→4.
Another question I was about to link to just got deleted; the OP asked how to find the points (x,y) that define an ellipse. (Note that this isn't actually a MATLAB question.) It was there until I mentioned to the OP that he/she needs to show that there has been some attempt at answering the question.
In my undergraduate and graduate experience as a non-programmer (my major is aerospace engineering, with a minor in computer engineering), any first language can be a hard one to learn, especially in an engineering class where the primary focus is not how to learn to program, but how to create numerical methods. At least in aerospace and mechanical engineering, MATLAB is introduced in the junior year and not really given a good treatment aside the absolute basics. Furthermore, SO is by design a site for programmers and most programmers don't use MATLAB as their base language; so I understand that there will be a lot of "homework-help" type questions as opposed to "real" questions. But there is no reason you can't attempt a homework and post what you've tried and asked for a helping hand, rather than "give me answer kthxbai"
I also see that a lot of people will just answer the question even though it's obvious the asker has not attempted the problem himself. Maybe it's because it's easy rep (if it ever gets awarded), but this flies in the spirit of answering homework questions on SO. I personally pretty much refuse to answer questions like this, but so long as users feed the fish, so to speak, I feel like MATLAB questions will get progressively worse and worse. It's hard to stay engaged in the community when I have to weed through these types of questions before finding a gem that truly deserves attention and effort.
Is there anything that can be done to curb this issue?
My idea/feature request: If a user has what would be negative rep (i.e., he was a new user and asked a question which was downvoted - I will without hesitation downvote any question in which no effort was made beforehand to solve the problem), any further questions he asks would be flagged for review. If the question is not of sufficient quality or smacks of "plz gimme answer", the moderator should inform the user that the question will not be posted and he needs to improve its quality. This reinforces that SO is not a dumping ground for the homework you can't be bothered to do; if you want to use it for homework, make sure you've attempted it first and don't just ask for an answer, but ask for guidance or tips or "can anyone see why what I'm doing is wrong".
