subject = "PO1"

"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.

在 MATLAB Online 中打开

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));
