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.

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

Meta threads have a tendency to grow large. This has happened several times before (the wishlist threads #1 #2 #3 #4 #5, and 'What frustrates you about MATLAB?' #1 and #2).
No wonder that a thread from early 2011 has also kept growing. After just under a decade there are (at time of writing) 119 answers, making the page slow to load and navigate (especially on mobile). So after a friendly nudge; here is a new thread for the things that are missing from Matlab.
Same question: are there things you think should be possible in Matlab, but aren't? What things are possible with software packages similar to Matlab that Matlab would benefit from? (note that you can also submit an enhancement request through support, although I suspect they will be monitoring activity on this thread as well)
What should you post where?
Wishlist threads (#1 #2 #3 #4 #5): bugs and feature requests for Matlab Answers
Frustation threads (#1 #2): frustations about usage and capabilities of Matlab itself
Missing feature threads (#1 #2): features that you whish Matlab would have had
Next Gen threads (#1): features that would break compatibility with previous versions, but would be nice to have
@anyone posting a new thread when the last one gets too large (about 50 answers seems a reasonable limit per thread), please update this list in all last threads. (if you don't have editing privileges, just post a comment asking someone to do the edit)

Similar to what has happened with the wishlist threads (#1 #2 #3 #4 #5), the "what frustrates you about MATLAB" thread has become very large. This makes navigation difficult and increases page load times.
So here is the follow-up page.
What should you post where?
Wishlist threads (#1 #2 #3 #4 #5): bugs and feature requests for Matlab Answers
Frustation threads (#1 #2): frustations about usage and capabilities of Matlab itself
Missing feature threads (#1 #2): features that you whish Matlab would have had
Next Gen threads (#1): features that would break compatibility with previous versions, but would be nice to have

In this article, we discuss how educators can adopt simulation, alternative hardware, and other teaching resources to transition lab-based classes to distance learning: https://medium.com/mathworks/tips-for-moving-your-lab-based-classes-online-1cb53e90ee00.

Do you teach a lab-based class? Please share your thoughts, questions, experience, and feedback on these ideas here. I also welcome you to invite your colleagues to join the discussion here.

One community within MathWorks that has been helping students continue their learning is MATLAB Student Ambassadors. Despite new challenges with transitioning to distance learning, student ambassadors have done a truly amazing job. In a blog that was published recently, I discuss 3 examples of the great things that our student ambassadors have done to aid distance learning. Click here to read the blog. I hope after reading this blog you share my level of admiration for these students.

I wanted to briefly share my experience in transitioning from a hands-on lab course to a virtual lab in MATLAB. Here at UMass Amherst, Mechanical & Industrial Engineering, we have a required undergraduate lab sequence, one during junior year and another during senior year. I teach the 2nd course, MIE 402, with a focus on measurements, data acquisition, system dynamics, and control.
The main idea behind our labs, in addition to the all too important hands-on experience, is to provide the students with a platform where they can validate and understand limitations of theoretical models from experimental data.
While the hands-on aspect was lost, we were able to create virtual experiments that consisted on Simulink models saved as protected files. In our protected models, students were able to assign input variables, decide on simulation parameters (e.g., integration parameters), and have certain outputs saved to the workspace. The key for making this a challenging lab was twofold: (1) Students were not told about the level of modelling detail inside the protected file (e.g., were dry friction or electrical inductance included?) and (2) each student was assigned a different set of model parameters based on their student ID (via a predefined table inside the protected file). The 2nd point was especially impactful as students felt as if they are working on their own experiment.
We developed virtual labs for a tuned mass damper and a DC motor experiments. Feedback from the students showed that they missed the hands-on experience but really liked being able to interact, as many times as needed, with the virtual lab at their time frame of choice, and have the ability to interact with us (grad assistant and myself) then re-run the experiment to test new ideas.
Some future developments that could significantly enhance the educational impact of such virtual labs would be the addition of real-time animation and increased level of modelling (e.g., data acquisition effects, electromagnetics, etc.’). At UMass we presently do not have access to the entire suite of MATLAB tools, something that prevented us from including these ideas in our virtual labs.
This would have not been possible without Andy Bartlett (tremendous Simulink help) and Div Tiwari (quickly getting us access to required tools).
