Variable as placeholder in an "fopen" statement

Still on the issue of a place holder , I am trying to write a code to name the output folder by subject name, I know typically it goes into the braces but this time arround it is not working

''

subject = "PO1"

fid = fopen(['/Users/addison/Documents/Data/"Results2"+{subject}.xls'],'w');

''

"I know typically it goes into the braces..."

with Python's Formatted String Literals: https://docs.python.org/3/tutorial/inputoutput.html#tut-f-strings

"...but this time arround it is not working"

which is not a big surprise with MATLAB.

The way I would do this is this

subject = "PO1";
folder = "/Users/addison/Documents/Data/";
filename = "Results2" + subject + ".xls"

filename = "Results2PO1.xls"

fid = fopen(fullfile(folder, filename));
