Is it possible to remove statements/lines from the command window (not everything)?

Is it possible to remove statements/lines from the command window (not everything)? I just want to clean up the window before taking a screenshot for an assignment submission, but I don't want to have to re-enter all the stuff I want to keep if I were to clear everything. Thank you for your assistance.

You can type clc to clear the window. Then you can type up arrow to execute only the commands you want to show in the window.

Alternatively you can use something like Photoshop to paint over stuff in the command window screenshot that you do not want to show.

Thank you for your answer.

What you suggest (clc and up arrow) is what I am doing now, but it's time consuming.

Are you saying that there is definitely no way of removing individual statements/lines?

Thanks, again.

Once you have executed a line of code and it reported its output to the command window, there is no way to delete it that I'm aware of. You can only prevent it from appearing in the first place, or post process the screenshot.

Another way to prevent stuff from appearing in the first place is to have the lines of code in a script. By using or not using semicolon and echo you can control what goes into the command window.

Thank you for the verification.

I'll try out your other suggestions.

Is there a place to make suggestions for adding features to MATLAB?

Thanks, again; you've been very prompt and helpful.

@Jeremy you can send an email to [e-mail]

Great! Thanks, again.

Thank you for the link, Walter. Good to know.

What I wanted to get rid of were error messages and the like. I would have a dozen statements and then mis-enter another one, ruining the screenshot.

Anyway, thanks, again.

You export the history to text and write to a file. You edit the text file to remove the mistakes and unnecessary steps. Then you execute the cleaned text, which will rerun the program

[Jeremy]

Thanks, again, Walter.

I have actually used that method, and it does work.

I was hoping that there was a built in feature of MATLAB, though, to make it more convenient and am going to suggest it to MathWorks.

I appreciate the help.

Rather than pressing up and executing each individual command one at a time you can select a subset of the commands in the Command History (using Ctrl if the commands you want to execute are not contiguous in the History or Shift if they are), right-click on the selected subset, and choose "Evaluate Selection".

The context menu will also allow you to create a script or live script with the selected commands if you want to turn the results of interactive experimenting into something you could publish, turn into a function to be reused with different inputs, etc.
