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?
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.
- If you don’t have your own equipment see one of our 1,000,000 existing channels. Check out over 200,000 public channels at ThingSpeak.com.
- Use the fitvirus program to fit COVID-19 data. You can download the fitvirus code on File Exchange. You can get your own data or download statistics from a public ThingSpeak channel with COVID-19 data. For other COVID-19 related resources see COVID-19 Research and Development with MATLAB and Simulink
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')
- Use ThingSpeak to Visualize your data. Consider a geographic plot to show location data with your measurements, or build your customized channel view.
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.
Below are some FAQs for the Cody contest 2020. If you have any additional questions, ask your questions by replying to this post. We will keep updating the FAQs.
Q1: If I rate a problem I solved before the contest, will I still get a raffle ticket?
A: Yes. You can rate any problem you have solved, whether it was before or during the contest period.
Q2: When will I receive the contest badges that I've earned?
A: All badges will be awarded after the contest ends.
Q3: How do I know if I’m the raffle winner?
A: If you are a winner, we will contact you to get your name and mailing address. You can find the list of winners on the Cody contest page .
Q4: When will I receive my T-shirt or hat?
A: You will typically receive your prize within a few weeks. It might take longer for international shipping.
Q5: I'm new to Cody. If I have some questions about using Cody, how can I get help?
A: You can ask your question by replying this post. Other community users might help you and we will also monitor the threads. You might also find answers here .
Q6: What do I do if I have a question about a specific problem?
A: If the problem description is unclear, the test suite is broken, or similar concerns arise, post your question(s) as a comment on the specific problem page. If you are having a hard time solving a problem, you can post a comment to your solution attempt (after submitting it). However, do not ask other people to solve problems for you.
Q7: If I find a bug or notice someone is cheating/spamming during the contest, how can I report it?
A: Use Web Site Feedback . Select "MATLAB Central" from the category list.
Q8: Why can't I rate a problem?
A: To rate a problem, you must solve that problem first and have at least 50 total points.
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.
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.

Hello,
I am a student. I am currently looking into graph neural networks (GNNs). My domain is electrical power systems. In electrical power systems, it is extremely important that we get an accurate desired output numerical value of electrical data from a neural network.
1) I have a basic question. Consider an electrical grid network of nodes. I am trying to learn this electrical grid network data using Graph Neural Network (GNN). Every node of a GNN accumulates data from neighboring nodes, then processes it by a few steps of an algorithm, and passes it to the next layer. Finally, data is passed through a non-linearity and then to the output layer of the GNN.
But, if I feed electrical data to the above process, the original value of data at every node gets manipulated by several processing operations, and especially after passing the manipulated data through a non-linearity at the final stage, the output is obtained only in the form of 1's and 0s. Hence, the original electrical data value at every node is totally lost. On the contrary, I am expecting an output of an "accurate" value of electrical data similar to original value electrical data at every node of the network.
How to address the above problem? Please explain systematically if possible. This is a genuine basic question.
2) Also, does anyone have a clue, why Graph Neural Networks (GNNs) have not been introduced yet as a toolbox or in general in Matlab?
Help and opinion on above questions would be greatly appreciated.

Thank you for your helping. I'm trying to import csv files form a folder, however it does not work.
The following code might be wrong.. fname=mtlb_dir('Users/shogo/Left_Leg_Single-Leg_Landing/SLLExport/*.exp')
I appreciate it if you help,
Sincerely, Shogo

Here's an thread on comparing various types of instructional labs (on-campus, virtual, remote, kits). Each type has pros/cons and things that you need to consider.
As an environment for modeling, simulating, and testing dynamic systems, Simulink is used for:
- Creating virtual simulation labs for interactively exploring technical concepts and building intuition in areas like controls , circuits , mechanics , and signal processing
- Collaborating and implementing software- and hardware-based projects in areas like robotics, instrumentation, and FPGA’s
Simulink is now available in a web browser as Simulink Online.
Simulink Online is available to anyone with access to MATLAB Online (see supported license types here) and a Simulink license.
Just sign into MATLAB Online and either start Simulink or open a Simulink model.
Learn more about Simulink Online at the product page on our website.
Simulink Online currently supports the following toolboxes, with more to be added in the future!
- Simulink
- Stateflow
- Simscape
- Simscape Electrical
- Simscape Multibody
- Simulink Control Design
- DSP System Toolbox
