If I wanted to act like an old fogey, I could reminisce and say I miss the good old days where we, at MathWorks, delivered demos by using the function echo. But I can't honestly say I miss that aspect of writing demos. These days, we either create GUIs, often light-weight for a demo, perhaps using guide or nested functions such as this example, OR, we write MATLAB code that we publish.
My question to you this week is: do you use the function echo currently? If so, can you please explain why/how (e.g., see no reason to update code, don't want to take the time to write a GUI, etc.). Thanks. As always, let me know your thoughts here.
