MATLAB Answers™ provides a collaborative environment for finding the best answers to your questions about MATLAB, Simulink, and related products. You can tap into the knowledge and experience of over 100,000 MATLAB Central members and MathWorks employees. Specifically, you can:
Before you ask a question, search to see if the question already exists or has been answered. You can use filters to refine your search. You can filter by status (answered, answer accepted, or unanswered), category, product, or date asked.
You can also use tags or search directives. All questions are tagged with one or more keywords to help community members find questions and answers of interest.
When searching for an answer, select the best answer based on usefulness and votes, which help indicate quality.
Tags provide bookmark information to help find or recall content. You are required to enter at least one tag when you ask a question. With tags, you can browse using assigned keywords. All tags are public; anyone can view them.
Search directives help you find content on MATLAB Answers. You can specify search directives in the search box or as edits you make to the URL.

Search directives can lead you to the right questions and answers quickly. If you use keywords in your search, results are sorted by relevance. Otherwise, results are sorted by date updated.
Multiple factors affect relevance, including:
tag:graphics tag:vectorsfinds all files tagged with both
-tag:gameexcludes all files with the tag
Before submitting a question, search to make sure it doesn't already exist. If your search did not provide an answer to your specific question, go ahead and ask it. The community is very responsive, so check back soon for answers.

Provide meaningful and descriptive answers to questions. If you are unable to answer a question because it is not clear, add a comment to the question requesting clarity or more detail.
Use comments to communicate with other participants about questions, answers, or comments. You can use comments to thank other contributors for answers to your questions or helpful comments.
Enhance your questions, answers, or comments with links or attachments.
You can upload:
A flag is a request for review that any contributor can assign to content. Contributors with sufficient privileges can then review and potentially revise, close, or delete the flagged content.
Questions, answers, and comments can be flagged if unclear, not appropriate, or spam.
Contributors with sufficient privileges are encouraged to improve the record or remove the flag (when the flag itself is inappropriate). The nature of the flag helps determine the action needed. This process helps improve the overall quality of MATLAB Answers. MATLAB Central administrators monitor the flagged content page regularly.
When someone provides a great answer to one of your questions, accept it to let that person know that you are happy with that answer.
MATLAB Answers keeps track of whether your questions have accepted answers and displays your Acceptance Rate on your home page. An Acceptance Rate of 100% means that you accepted at least one answer for every question you asked. If your Acceptance Rate is below 100%, take a look at your questions and see if any of them have wonderful answers that you want to accept. If you have not received any acceptable answers to a question, consider clarifying or adjusting the question to help others find an answer.
Note: If you accidentally accept an answer for a question or you accept an answer and later find a different answer is better, you can unaccept an answer. Until you accept a new answer, your Acceptance Rate will go back to what it was before you accepted an answer for this question.
As you earn reputation points on MATLAB Answers, you also earn the ability to perform more significant tasks. You can check your profile page to view the reputation points and associated privileges you’ve earned. From this page, you can also check the points required for the next level of privileges. Note that administrators managing the system and editors with previously earned reputations have all privileges.
Editing and deleting questions, answers, and comments requires a high number of reputation points, as shown below. The objective of editing is very simple; make content clear, specific, and short. Good questions lead to good answers and result in a searchable archive with lasting value.
Note: Contributors who have earned sufficient privileges may edit and delete questions, answers, and comments at their discretion. This includes removal of personal attacks, spam, and inappropriate or off-topic content, and unaccepting answers. If you unaccept an answer, there is no loss in points.
