Most variables can be cleared by
var = [];
When I treid to do the same thing for my file name and path like below:
app.File.Value = [];
app.Path.Value = [],
I get this error:
Error using matlab.ui.control.EditField/set.Value
'Value' must be a character vector or a string scalar.
What is a better way of clearing these two variables? Thanks!

Use '' or "" as the value instead of []
