controlling what gets saved in command history

I have a function that asks user (using the "input" function) if they want to enhance a plot and/or print the figure. There are several prompts and response processing steps in the function. My problem is that all the user responses get saved in the command history (along with whitespace lines) making the command history cluttered up with these lines of (usually) 1 character responses to input prompts. Is there a way to turn command history recording on/off (like you can do with "diary")?
I would like to turn command history recording "off" at start of my function and then back "on" at the end of the function to avoid capturing the keyboard input response to the prompt in the command history. Alternatively, but less desirable, can you make the "input" function not echo back the user response?
Any ideas?

You could use the method described in this post to disable and enable the history. Unfortunately, it seems that preference only affects what gets saved from one session to the next. Commands entered during the current MATLAB session are recalled regardless of the setting.

I can't think of a way to do what you want but I have entered this into our database of possible future enhancements.

input() does not echo the user response:
disp('before');
reply = input('What is the number? ');
disp('after');
The output ist:
before
What is the number? 90
after
No blank lines, no echo.
The command window is not a good interface for user input. Better create a GUI.
