# The MATLAB Online Live Editor Challenge14

Posted by Loren Shure,

Today I’d like to introduce a guest blogger, David Garrison, who is a MATLAB Product Manager here at MathWorks. Dave will talk about an exciting new contest for students and faculty where you can win a cash prize by showing us what you can create using the Live Editor in MATLAB Online.

### Contents

#### Show off your live script and win!

Hello everyone. Loren has been kind enough to let me use her blog to tell you about the MATLAB Online Live Editor Challenge. The challenge is open to students and faculty of any college, university, or degree-granting institution. It's an opportunity for students to win up to $750 and for faculty to win up to$1000. Simply show us how you would use the Live Editor in MATLAB Online to create a live script on a topic of interest to you.

For students, pick a topic you've learned about in a class or from a research project or pick a concept in science, engineering, math or anything else that interests you.. For faculty, select a topic in your area and show us how you would teach that topic using a live script. You can work individually or in teams and submit as many entries as you want. We’ll judge each entry on things like presentation clarity, topic uniqueness, creativity, and effective use of Live Editor features. If your entry is a winner, we'll feature your live script on our website and you'll receive a cash prize.

#### MATLAB Online

For the challenge you'll be using MATLAB Online to create and share your live script. With MATLAB Online, you can use the latest version of MATLAB in your a web browser without installing, configuring, or managing any software. You can check your eligibility to use MATLAB Online here.

Here's an example live script that I wrote in MATLAB Online for estimating sunrise and sunset times.

#### How to Enter

To enter the MATLAB Online Live Editor Challenge, follow these three easy steps.

1. Submit an entry form. Don't forget to do that because we can't consider your entry without it.
2. Use the Live Editor in MATLAB Online to create an original live script on a topic of your choice.
3. Put your live script and any supporting files in a folder in MATLAB Online, then share that folder with studentcompetitions@mathworks.com.

That's all you have to do. The deadline for entries is June 29, 2018 (7 a.m. ET). For complete details and contest rules, go to www.mathworks.com/academia/student-challenge/matlab-online-live-editor-challenge.

Good luck! We look forward to seeing what you create with the Live Editor in MATLAB Online.

Can postdocs enter?

David Garrison replied on : 2 of 14

Yes, postdocs can enter. Please enter as a faculty member and show us a live script you would use to teach a topic in your area.

In order to fit students Live Editor must be improved in 2 things:
1. Have support for MarkDown.
2. Have support to write Inline Math using $LaTeX Code$ and Display Math using $$LaTeX Code$$.

This matches Jupyter and will make things easier for most.

Currently it takes too much time to write Math using the wizard.

You can add equations using LaTeX. From the Insert tab, select the Equation dropdown. You have two options — enter your equation as LaTeX or use the interactive equation editor.

David,
I know what you suggested and this is exactly the issue with Live Editor.

What’s needed is a smoother user experience using $…$ and $$…$$ escapes as in Jupyter.
Or at least make is also valid.

This box is just unneeded extra clicks.
Jupyter is perfect, just Copy & Paste.

David Garrison replied on : 6 of 14

OK. Thank you for your feedback.

Royi Avital replied on : 7 of 14

It seems the comment masks out some of the text.

I meant I want to use something like that for Display Math:

$$LaTeX Code$$

And something like that for Inline Math:

Inline Math $LaTeX Code$.

I hope this time it will work and will be displayed correctly.

Nice challenge, but if I’m (a student) participating with a faculty member, should we enter as faculty or student?!
By the way, the hyperlink provided before “Goodluck!” does not work. (Technically speaking, it happens when you don’t use “https://” in the link)

David Garrison replied on : 11 of 14

Reza, if the live script you are writing is attended to be used in the classroom, then have your professor enter as faculty. If the live script describes a research project you are doing with a professor, you should enter as a student.

David Garrison replied on : 12 of 14

Royi, you can type LaTeX equations directly in a text region by typing $\sum x^2$. As soon as you type the second \$ sign, the Live Editor will render the expression as LaTeX inline math. If you do the same thing at the beginning of a new line, the Live Editor will render the expression as LaTeX display math. That display math expression can then be left, center, or right aligned.

Hope that helps.

Thank you very much for the opportunity. I would like to know weather the people who are working as early stage researcher in research based companies can enter as well?

Harshitha, this version of the contest is for students and faculty only. We may do another contest in the future where we open it up to folks outside of academia.
