See what's going on at MATLAB Central without leaving MATLAB 🙂

Here's a MATLAB class I wrote that leverages the MATLAB Central Interface for MATLAB toolbox, which in turn uses the publicy available Community API. Using this class, I've created a few Favorites that show me what's going on in MATLAB Central - without having to leave MATLAB 🙂

The class has a few convenient queries:

Results for the last 7 days
Results for the last 30 days
Results for the current month
Results for today

And supporting a bunch of different content scopes:

All MATLAB Central
MATLAB Answers
Blogs
Cody
Contests
File Exchange
Exclude Answers content

The results are displayed in the command window (which worked best for me) and link to each post. Here's what that looks like for this command

>> CommunityFeed.thisMonth("app designer", CommunityFeed.Scope.ExcludeAnswers)

Let me know if you find this class useful and feel free to suggest changes.

Naming x-values in bar(x,y)

I know the latest version of MATLAB R2023b has this feature already, put it should be added to R2023a as well because of its simplicity and convenience.

Basically, I want to make a bar graph that lets me name each column in a basic bar graph:

y=[100 99 100 200 200 300 500 800 1000];

x=["0-4" "5-17" "18-29" "30-39" "40-49" "50-64" "65-74" "75-84" "85+"];

bar(x,y)

However, in R2023a, this isn't a feature. I think it should be added because it helps to present data and ideas more clearly and professionally, which is the purpose of a graph to begin with.

Implicit expansion for CAT()

Would it be a good thing to have implicit expansion enabled for cat(), horzcat(), vertcat()? There are often situations where I would like to be able to do things like this:

 x=[10;20;30;40];
 y=[11;12;13;14];
 z=cat(3, 0,1,2);
 
 C=[x,y,z]
 

with the result,
