Permission denied when I write an audio file

I created a variable 'z' and I flipped an variable containing an audio and I assigned that flipped data to the variable 'z'.

When I tried to write that variable 'z' as an audio file I am getting this error

"Permission denied".

This is what I did-

 wavwrite(z,'audio.wav');

Do you have write permission in the current directory?

[Walter Roberson]

Windows 7? If so then what directory name are you trying to write into?

Do you have write permission in the directory you are trying to write the .wav file?

Is a .wav file by that name and in that directory already open in some other program?

If the above are not true, please show the size and class of z.

Answer 2

right click on the matlab icon and run as administrator
