We have created a new distance learning community for educators who are teaching remotely or online using MathWorks tools. It houses resources, such as articles, code examples, and videos, as well as an area where community members can ask questions or hold discussions around best practices in distance learning. Jiro Doke , who also writes for the File Exchange Pick of the Week blog, will be moderating this community.

We encourage you to visit the new community and share best practices, examples, and ask questions.

We have created a new page in MATLAB Answers that aggregates the most frequently asked MATLAB questions (FAQs). FAQs are common and a good starting point for anyone learning something new and having them all in one place can be a useful resource. Our new FAQ page lists the top 100 MATLAB questions asked and answered in MATLAB Central . They are grouped into the following 9 categories:

• Data Import and Analysis
• Graphics: Basics
• Graphics: Objects
• Installation and Licensing
• Language Fundamentals: Basics
• Language Fundamentals: Matrices and Arrays
• Language Fundamentals: Operators and Elementary Operations
• Mathematics
• Programming

I recommend that everyone scans the new FAQ page as you might find some useful tips.

We will be updating the FAQ page regularly as new questions are asked in the community. We welcome any feedback you have.

Hello Distance Learning Community!

I am hoping to hear from any academics in how MATLAB's online resources have helped you during this difficult time of transition to online courses:

- Have you had any issues or difficulties with getting started with our online tools?

- Do you see any areas of improvement that could better serve your course in an online environment?

- Do you have any stories to share of how these online tools have helped you to run your class and improve it for the future?

Thank you and stay well!

Hello everyone,

I’m Jiro, and I’m part of the Education Customer Success group at MathWorks. We help academics, students, and institutions achieve success through the use of our tools. I will be the moderator for this new community of distance learning.

As many academic institutions are moving their classes online, we hope that this community will help instructors connect with others who are in the same situation. This community site gathers various resources and information that will be useful for teaching with MATLAB and Simulink in a distance learning setting. We have a number of MathWorks employees monitoring this community, but we want this to be a place for the community to come together. The hope is that the community will grow and the resources gathered here will grow with it.

I encourage you to share best practices ( Discussions ), ask questions ( MATLAB Answers ), and share examples ( File Exchange ).

As a first question, what course are you teaching (or planning to teach) online?

Hello friends i have strugled to develope codes in matlab and spent ample time in converting the available codes to my area . If any of the researcher are interested to share their codes with me are welcomed and collabarations are welcomed ...currenty i need a basic code in unit commitment using real coded and binary coded for Security contrained and integrating Reneweable energy .. I too will share my codes because world is going to vanish soon so my knowledge should spread across the globe

Let me know what you think. Arkadiy

Hi everyone,

I am trying to control an actuator with brushless DC Motor in Simulink. At one point, I am in need of the motor rotation and the only parameter available to me is the duty cycle and the direction of rotor. I knew that it is not possible to calculate rotation from duty cycle. In case if some one have idea about this or some suggestions, could you please share with me

Thanks in advance

Hello,

I am trying to simulate a PMSM, which has a Quasi sinusoidal back-emf waveform. Is there any way I can define the back emf to be anything other than Sinusoidal/Trapezoidal?

Thanks in advance. Saurabh Kumar

Check out this pick of the week from Will. Steve's progressbar submission has been around since 2005 and still runs perfectly. Check out the blog post to see why Will picked it.

Recently, I have been learning the mathematical modeling of switching converters. Looking for a lot of data, I know that the current loop control mainly includes peak current, valley current and average current control methods. The detailed process of peak current modeling is found in the book "modeling, control and digital realization of switch converter". However, my brother has not found the detailed introduction of average current modeling. I would like to ask you brother and sister have any good information recommendation, the best is books (the most detailed explanation). Thank you very much!

I have issue with the design that i have downloaded from mathwork community. how to solve regarding this matter

Hello everyone, I am trying to implement 3 level space vector modulation for a multilevel inverter. Without mapping vector for region selection of three level space vector, I am getting reference angle started from sector-1 to sector-6 as shown in ''theta_ref'' file. But when I am implementing mapping references for region selection (please see in the attached file ''mapping_reference''), the reference angle is shifting 180 degree that means it is starting from sector-6 to sector-1 as in attached file ''theta_ref_with_region_identification''. Could anyone please let me know why this is happening and how to solve this problem?

Thanks in advance.
