What are the first steps to developing a new toolbox?

Imagine you are developing a new toolbox for MATLAB. You have a folder full of a few .m files defining a bunch of functions and you are thinking 'This would be useful for others, I'm going to make it available to the world'

What process would you go through? What's the first thing you'd do?

I have my own opinions but don't want to pollute the start of the conversation :)

Fun

All you need is....

tiledlayout(4,1);

% Plot "L" (y = 1/(x+1), for x > -1)

x = linspace(-0.9, 2, 100); % Avoid x = -1 (undefined)

y =1 ./ (x+1) ;

nexttile;

plot(x, y, 'r', 'LineWidth', 2);

xlim([-10,10])

% Plot "O" (x^2 + y^2 = 9)

theta = linspace(0, 2*pi, 100);

x = 3 * cos(theta);

y = 3 * sin(theta);

nexttile;

plot(x, y, 'r', 'LineWidth', 2);

axis equal;

% Plot "V" (y = -2|x|)

x = linspace(-1, 1, 100);

y = 2 * abs(x);

nexttile;

plot(x, y, 'r', 'LineWidth', 2);

axis equal;

% Plot "E" (x = -3 |sin(y)|)

y = linspace(-pi, pi, 100);

x = -3 * abs(sin(y));

nexttile;

plot(x, y, 'r', 'LineWidth', 2);

axis equal;

On love and research software: Learning about research code sharing for Valentine's day

For Valentine's day this year I tried to do something a little more than just the usual 'Here's some MATLAB code that draws a picture of a heart' and focus on how to share MATLAB code. TL;DR, here's my advice

Put the code on GitHub. (Allows people to access and collaborate on your code)
Set up 'Open in MATLAB Online' in your GitHub repo (Allows people to easily run it)

I used code by @Zhaoxu Liu / slandarer and others to demonstrate. I think that those two steps are the most impactful in that they get you from zero to one but If I were to offer some more advice for research code it would be

3. Connect the GitHub repo to File Exchange (Allows MATLAB users to easily find it in-product).

4. Get a Digitial Object Identifier (DOI) using something like Zenodo. (Allows people to more easily cite your code)

There is still a lot more you can do of course but if everyone did this for any MATLAB code relating to a research paper, we'd be in a better place I think.

Here's the article: On love and research software: Sharing code with your Valentine » The MATLAB Blog - MATLAB & Simulink
