end

it produce a error " Undefined function 'writes' for input argument type 'char' "

There is no fundamental problem with your syntax, so the only possibility is that Matlab can't find your function.

Live editor functionality changes a lot across versions, but my suggestion would be to put your function in a separate cell from the call, and make sure the function cell gets evaluated before the call line.

I will do that.

Thank you for your help
