type which place

The result should be somethign like this: "C:\Program Files\MATLAB\R2019b\toolbox\control\ctrldesign\place.m"

Verify that you have the Control Toolbox by typing ver. The result should be somthing like this:

If you don't have the Control System Toolbox but have access to it, use the Add-Ons menu in the Home tab toolstrip to get it.

[SL: removed the license number. Your license number should appear where YOUR_LICENSE_NUMBER_HERE appears.]

I get place.m file from another user and copy it there and it worked.

It's better to use the Add-Ons menu to reinstall the toolbox.
