As the title, I don't want to execute cmd in a specified or specific directory, but it can be executed no matter which directory I execute the file in.
How can it be modified?
out = fileread('1.txt');
cmd = ['xxx.exe', out];
system(cmd)
THX

You can but
  1. Files shold be in present working directory
  2. Program(here xxx.exe) should set to environmental variable if it is not present in the present workind directory
Code
cmd = ['xxx.exe', ' ', '1.txt'];
system(cmd);

I may not express it well enough. I mean that no matter where my xxx.exe is, it can be executed through matlab without adding a path in front. (Example: C: \ Users \ xxx.exe)

Set xxx.exe as environmental variable, then execute your code

You should add the directory containing the executable to the PATH environment variable.
