fopen only returns -1

Hi,

I'm trying to read some files (wave-files, but I also tried text) with fopen, but it always returns -1, ie. there is an error. It worked fine when selecting a .m-file. What am I forgetting? I use

fopen(uigetfile)

Edit:

It seems to have to do with the uigetfile. When I enter the path directly, it works fine. However, I don't understand, why, since I do select the specific path with uigetfile, don't I?

[filename, filepath] = uigetfile();
fullname = fullfile(filepath, filename);
fid = fopen(fullname);

Your version would only have been getting the file without its directory. When you use the single output version of uigetfile, uigetfile does not output the fully-qualified name.

Thank you! I was kinda suspecting something like this, but didn't know how to fix it. Your code works.
