Cody has a wealth of problem groups that allow users of various skill levels to improve programming skills vis-à-vis MATLAB in an engaging way.

I would like to highlight the Draw Letters group, composed of problems created by Majid Farzaneh.

If you haven't yet visited Cody or solved that problem group, I would recommend that you head over there now. What are you waiting for?

Hi, all friends

I am dealing with a confusing NCA result. As this result shows, AUC_infinity=0.8537 (μg*h/mL), DM=1 (mg). CL should be equal to DM/AUC_infinity but why is the calculated result 2.4491? There is no dimension along with value so I do not know if I ignore anything.

Does any one can handle with this situation? Thanks very much. I also post my used data (i.v.).

MATLAB Online lets students run MATLAB without having to install the software on the computer. All you need is a web browser and an internet connection.

I would love to hear comments and experiences of using MATLAB Online.

Hi, all friends

If I define a parameter, like solubility with dimension of milligram/milliliter and I want to refer it in an reaction equation in dimension of millimole/liter, suppose I have define its molecularweight, could I input this parameter directly in equation with specified dimension?

Question: How to load a host of variants created through scripts to a sbproj file so that we can simulate and visualize them through the simbiology GUI.

Description : In a typical QSP workflow, we generate virtual patients by perturbing a set of parameters. These virtual patients are generated as variants by using "addvariant".

We end up with an array of variants saved as "variants.mat". This mat contains the list of ~3000 variants.

These variants are now to be simulated with different dose objects. This could be done with scripts but it would be ideal if we import these variants into the sbproj file and simulate via simbiology GUI for both purpose of troubleshooting and dosing.

Is there a way to do this?

The Webinar has ended, but you can view the recording here on YouTube.

MathWorks has developed several cloud-based tools to enable instructors and students to have access for teaching and learning anytime, anywhere. Join us for a free webinar with Dr. Elvira Osuna-Highley where we’ll discuss these tools, how they fit together to support your course development and delivery workflow, and how to use them immediately in your online course.

We will discuss several resources including:

• Accessing MATLAB Online and MATLAB Drive Anytime, Anywhere

• Leveraging interactive content with self-paced courses, MATLAB Apps, and Live Scripts

• Mentoring students at scale with automated assessment and feedback in MATLAB Grader

• Connecting students with the community by participating in the MATLAB user community

Thank you to IFEES, GEDC and IUCEE for sponsoring this series to help support educators across the world in moving their courses online.

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?

Hi, all friends

I am working on building a oral model with "Generic SimBiology PBPK model" and meet some problems about intestinal transit rate. Take duodenum as example, the transit rate is defined as " (kTransportSmallIntestine*organismLengthDuodenum/organismLengthSmallInstestine)*Duodenum.DrugDissolved". I think assuming duodenum transit time is equal to SmallIntestineTransittime*organismLengthDuodenum/organismLengthSmallInstestine, the transit rate constant is the inverse of that,which result in kTransportSmallIntestine*organismLengthSmallInstestine/organismLengthDuodenum, contradicting with the equation in model. Am I wrong?

Besides that, the kTransportSmallIntestine_is defined as _0.693/organismMeanResidenceSmallIntestine in model. Isn't the mean residence time determining the time at which about 63.2% of initial amount having passed through the compartment and inverse of mean residence time determining the transit rate? Why does organismMeanResidenceSmallIntestine correlate with 0.693 which is often seen in half-life associated expression?

Thanks for any comment.

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

Hi, fellows,

I am a new user of MATLAB and SimBiology. When I open the "Generic SimBiology Physiologically-based Pharmacokinetic (PBPK) model" downloaded from "https://ww2.mathworks.cn/matlabcentral/fileexchange/37752-generic-simbiology-physiologically-based-pharmacokinetic-pbpk-model", I get a note of "Copyright 2012-2018 The MathWorks, Inc. ...". Does that mean I can not access to the model built-in or make any modification?

Thanks for any comment!

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
