This is a great presentation from 2 professors introducing how they use MATLAB in their physics courses. MATLAB Grader and Live Scripts are discussed in detail.

YouTube Video

Here is the abstract:

-----

Guest Presenters: Michele McColgan, Siena College and Duncan Carlsmith, UW Madison

The meeting will start with short presentations, and then we'll have time for questions and discussion in a colloquial setting. The presenters use MATLAB in their courses, and this meeting will provide a good opportunity to see the functionality that MATLAB affords. However, the presenters' approach to integrating computation is relevant generally; thus, this meeting should be of great interest, even if you are not a MATLAB user.

Is anyone else disappointed with uifigures? It seems apparent that these will eventually replace traditional figures, but there is still so much that doesn't quite work. I've tinkered with uifigures since their introduction in release 2016a, but even in 2020a I can't reliably export a uifigure to a graphics file. Sure it works sometimes, but not if a uipanel is present. The exportgraphics command is not as powerful as the print command, leaving some graphic formats (such as *.svg and *.eps) unsupported. How do you generate graphic files of a specific size? You can't even use subplots without overriding the default AutoResizeChildren setting!
Everything with uifigures seems to be slower and less stable than the figure variant. App Designer is much better than GUIDE, but that is not exactly high praise. I would rather generate "apps" programatically across several files instead of dealing with a single-file class definition containing 1000+ lines.
Where is this transition going? MATLAB graphics are moving away from Java in favor of JavaScript, and I'm not sure that we are at all ready for that.

WiDS Datathon 2021 is going on right now. The focus of the Datathon this year is "on creating models to classify whether patients have been diagnosed with a certain type of diabetes." You can register and participate until March 1.

Also, take a look at this blog post on the MATLAB benchmark code for this datathon.

There are also various online challenges by MathWorks that students may be interested. Here are the winners from last year's Simulink Student Challenge. There was also a MATLAB Online Live Editor Challenge a couple of years ago.

Discrete or continuous time model

Hello , I wonder how to determine continous or discrete time modelling.For example if I want to run my model in MCU in this case discrete model is suitable?I am a bit confused

Happy New Year, everyone! We hope you enjoyed the Cody contest in 2020, learned new MATLAB skills, and made a friend or two. While the 2020 contest has concluded, the fun and learning never end.

Please take the 1-minute survey to talk about your experience (only 2 required questions). Our goal is to make future contests better and more appealing to you, so your feedback is critical to us.

Thank you in advance and hope to see you again in the 2021 contest.

I am currently working on simulink online but I cannot maximize the screen

Just making sure people are aware of our new Onramp courses. These are great self-learning resources for students.

Released a few months ago:

Released this month:

How do you teach subjects like Programming and Numerical Computing hands-on in these challenging times?

Prof Chiranjoy Chattopadhyay at the Dept of Computer Science and Engineering at IIT Jodhpur shares his innovative approach to teaching at a distance in this new Technical Article on Teaching Parallel Computing Online with MATLAB.

The course utilized MATLAB Online , MATLAB Onramp and MATLAB Grader to train students in the basics of technical computing, in addition to using a Hands-on Online GPU workshop organised with the MathWorks Education Team. As a result of this approach to distance teaching, the students have reported good levels of understanding in the main learning outcomes of this course, as indicated in the survey results (below):

Please consider trying out the links above to check if your course might benefit from a similar approach, and feel free to message us if you are interested in learning more.

Emulating a physical experiment

I just highlighted an app on File Exchange for emulating an experiment. Great idea for doing lab classes with software. What I like about this app is that it incorporates statistical variance and measurement noise that comes from physical experiments.

Discrete vactors plotting problem

I would like to plot 2 discrete vectors on one graph created as follows: u=1; X={u,2*u,3*u,4*u,5*u,6*u,7*u,8*u,9*u}; Y={u,3*u,5*u,-u,-6*u,u-u,u^2,u^3,u^4}; stem(X,Y) unfortunately system returns error how to do it properly?

Here's a short article describing how educators from UNSW have used Live Scripts to help students understand mathematical models. Interactive live scripts allow students to experiment and understand concepts through trial and error. The article also explains how the scripts helped provide an enriched online learning experience for the students.

Do you use Live Scripts in your teaching?

Copy-Paste in Grader

I often code snippets to students in the question description. I would like the students to be able to copy and paste these from the description into their solution, obviously all on the same web page. I thought this was the case before, but now Ctrl+C/V do not work and when I right click there is no copy/paste options. Is this not possible?

Cody Contest 2020 Starts Today!

We are excited to announce that Cody Contest 2020 starts today! Again, the rule is simple - solve any problem and rate its difficulty. If you have any question, please visit our FAQs page first. Want to know your ranking? Check out the contest leaderboard .

Happy problem-solving! We hope you are a winner.

One great thing about IoT projects is they are connected to the internet, and that creates an opportunity to collaborate at a distance. Here are resources to help you teach classes that involve remote learning.

  • Record and visualize your experiment's data in ThingSpeak channels. For example, this public soil monitor channel shows measurements from a sensor connected to a plant. You can see the ThingSpeak example pages for help getting your experiment connected.

Figure 1: Fitvirus sample results.

When you can’t make it into the lab, use ThingSpeak to monitor and control your lab equipment for experiments and for teaching.

  • When you use ThingSpeak channel values to control your hardware modes, students can run experiments from home, and even collaborate with others to control devices and collect data for analysis.

Figure 2: Sample ThingSpeak lab model.

  • Build a simulation model to deploy on hardware and control it remotely. Watch this video to see how you can do both simulation and deployment in the same Simulink model. You can also download the models used in the video.
  • Use ThingSpeak to analyze your data. Use the provided code templates (like this one for removing outliers from wind speed data) or custom MATLAB code to filter and analyze your data and schedule it to run at regular intervals.

regularFlag = isregular(data,'Time')

Save an Image from MATLAB Grader

I get students to create some figures in MATLAB Grader. Is there anyway the students can save the figure on their computer? I have tried savefig and that doesn't seem to do anything.

Remote access robotics lab

Take a look at this video on remote access robotics lab. It allows students to submit algorithms and have them run on a robot completely remotely.

Robotarium

Here (16:56) is where the submission process is explained.

Professor Christophe Demaziere from Chalmers University of Technology, Sweden created a short course on nuclear reactor modeling.

  • The course followed a flipped and hybrid approach last year but will most likely be taught entirely online in future due to Covid-19 pandemic.
  • MATLAB Grader greatly facilitates the Online nature of Christophe's courses.
  • Student Feedback was also very positive saying that they learned better compared to the traditional approach.
