I was wondering if there's anyone out there who can help me with this problem. I have a simple script that I use to clean my workspace as follows:

clc
d=input('close figures? (y/n) ','s');
if d=='y'
close all
elseif d=='n'
display('no figures deleted');
else
error('enter proper flag');
end
clear

Now I want to delay the effect of the last command "clear", so that if any person uses this script other than me can be able to see the text "no figures deleted" if "n" is chosen. As it is now, everything disappears in the blink of an eye. Any suggestions?

Thank you.

If I choose 'n' in your script, I can see "no figures deleted". Nothing disappears on the display of my computer after a CLEAR command. CLEAR clears just the variables and functions from the workspace, but it does not celar the screen as your initial CLC command.

Kind regards, Jan

thanks a lot for your quick response. 'pause' indeed is one of the options i could use, but like the name says it pauses execution of a script or function until the user intervenes by hitting the enter button. in my case, i do not want the user to do that, because then i'd have to let the user know that he has to press that key. i'm just looking for a way to do the countdown, say from 3s to 0s, until 'clear' command is executed.

Thanks pointing that out Jan. in fact, i copied and pasted the script i was still working on. the original one had 'clear' at the top and 'clc' at the very bottom. sorry for the confusion.
