My thinking was that this:
fprintf('Test %d',1)
pause
clc
fprintf('Test %d',2)
pause
should:
  • Print "Test 1"
  • Wait for the user to press a key
  • Clear the Command Window and print "Test 2"
  • Exit when the user presses a key
However, "Test 2" is never printed. Instead a blank screen is displayed. What am I missing?
I'm using MATLAB Online (R2019b)

I've had this happen to me before where a command immediately after a clc will print to screen, but then get cleared anyways. It's like MATLAB calls the clc function behind the scenes, runs the fprintf command, and then the clc actually executes.
I wonder if the issue will be solved if you add drawnow() after the clc. Let me know!

works as expected when I try it in R2019b.

Tried the drawnow() but no luck. It definitely works if the pause is replaced with an input(''), but I'm just curious why the original code doesn't work.
Perhaps you're correct and a clc executes after the next buffer flush?

Any chance you can try it in MATLAB Online just to verify it is having an issue on there?

Hi,
I have brought this issue to the notice of our developers. They will investigate the matter further.
