cannot find the subfolder created by mkdir command (MATLAB R2017b on Mac)

I used the mkdir command to create a subfolder under my current folder, as follows: mkdir newdir I could see that in the command window when I type in dir command, but cannot find it in my finder on Mac (file manager on Windows) and cannot save a file under that folder too.

Is there a way that I could effectively create a subfolder and save files in that folder?

Hi Frank,

If you run the following command, what output do you get?

[status,msg,msgID] = mkdir('newdir')

Can you 'cd' into the new directory after using "mkdir"?

In addition, what error message(s) do you see when you try to save a file into that new folder in MATLAB R2017b?

Thank you very much. The code you provide works well. I could see that folder now. However, I don't understand why lol.
