When I use matlab code to compile this program, it will display please read the wav file, but when I use deploytool to generate an exe file, it will not ask me to read the wav file, and an error appears. How can I solve it?
how to read wav files on the exe file generated by matlab code?
Drag the picture to the side, there is an error message about running the exe file
thanks!

  1. Do not use "clear all" in deployed code. Best is if you do not use "clear all" at all.
  2. Use uigetfile() instead of prompting for input. There might not even be an input() stream, depending how you compiled the application.
  3. Your current directory is quite likely to not be where you expect. You might want to go to the trouble of figuring out where the user's home directory is to use that as part of the uigetfile() so as to provide a reasonable default. For Windows, get the environment variables HOMEDRIVE and HOMEPATH to construct the full path to the user's home directory; for Mac and Linux, get the HOME environment variable.

audioread() should work, provided that you pass in an absolute path. Make sure you use fullfile() with the directory and filename returned by the uigetfile() call. Also make sure you test that the returned filename is not numeric, as numeric indicates that the user canceled the uigetfile()
[filename, filepath] = uigetfile(....)
if isnumeric(filename)
user canceled, respond appropriately
end
location = fullfile(filepath, filename);
[audio, Fs] = audioread(location);
