Hello!

i had a code with was opening some files in the folder the m files was in, i did it like this:

bat_ip = fopen( bat_name, 'wt' );

i don't know how, but it stop working. the file is still opening, beacue fopen is returning a number difrent that -1, but the file that was open is not in the folder the m files is in, where i wish it to be.

any one know what could change and how can i returen it to open from the place the m file is located?

thank you!

maybe you have issues because you ran your code multiple times and tried to open the filename mutiple times. dont forget to use fclose(fileID) or if you dont know the id you can use fclose('all')
