% Additional lines of first comment are reported by 'help' % First comment line is reported by 'lookfor' The general syntax of a Matlab function is as follows:įunction = functionName( inarg1, inarg2.As a consequence, functions have mechanisms for passing arguments into the functions, and for returning the results.Variables defined and used in a function do not affect the regular Matlab workspace. Functions, however, define a separate ( local ) scope.Any variables created get added to the workspace, and may replace other variables that were already defined there with the same names. Ordinary script files have the problem that they run in the scope of the command window.Both are plain ASCII files containing Matlab commands, with '.m' file extensions.Matlab function files are very similar to Matlab script files, with a few important differences.Etter, 'Introduction to MATLAB, Second Edition', Section 3.6.

Thanks to the efforts of customers like Angel, our notification system provides approximately 30% of customers who report a crash with fix information that gets them unstuck within minutes. In the case that we do not have a fix, we will connect you with our Technical Support team to help you troubleshoot the crash. If we fix it, we will tell you and anyone else who reports it. If you send your crashes, we are going to analyze them. Even if you don’t have anything to share, press Send.Sometimes minimal information about the functions you are using or the type of system you have can be bread crumbs that can lead us to the solution. When you do send a report, tell us ANYTHING you can think of that might be relevant to the crash.When you press Send, you may be more like Angel (who got us started on a problem) or Ian (who got an immediate fix). This is a story about how Angel helped Ian and others like him without even knowing it. To this day, over 300 other MATLAB customers have benefitted from the efforts related to identifying and resolving this one bug. Ian was happy: “THANK YOU! That worked perfectly! I appreciate how quickly you replied to my issue!” Five minutes later, Ian received an email with the workaround information: The following week, Ian experienced this same crash. This had a dramatic impact on a customer named Ian.

Now when another customer reports a similar crash, they can get immediate information on how to resolve the bug. Then, Nick cataloged the workaround information into our notification system. At this point, Scott identified and validated a workaround. These interactions helped Scott learn that MATLAB R2017b introduced an incompatibility with a combination of a Linux distribution and a graphics driver. For several weeks they explored different ways to narrow down the issue. Tushar, together with our developer Scott, began troubleshooting with Angel. Nick reached out to Tushar, one of our technical support engineers, for help contacting Angel to try to understand what caused the problem. Nick, one of our engineers in charge of analyzing these reports, noticed the spike and began investigating.

Soon after, MathWorks began receiving similar reports from other customers. His crash report was sent off to MathWorks. Happily for our story, Angel decided to press Send. Late September of last year, a customer named Angel upgraded to MATLAB R2017b. Let me share a story to show you that good things can happen when you send us a crash report. Others assume no one will look at the report. Some people are concerned about information privacy. We know that people often hesitate to send these kinds of reports. I’m one of the people here who sees it and tries to do something useful with it. Press it, and you’ll send a crash report to MathWorks. If you look closely, you’ll see the first button says “Send”. If not, I’m glad! If so, I’m sorry, because this is the screen you see when MATLAB crashes. If you use MATLAB a lot, you may have come across a screen like this… Part of my job is helping people when MATLAB crashes.

His current focus is on helping customers who encounter MATLAB crashes and working with developers to improve MATLAB & Simulink. He likes solving challenging problems, and enjoys seeing his efforts help people. This week we have a guest post from Cesar Rivadeneyra.
