Hi all, I'm having a simple code problem ,here is the code:
% create an example sound
t = 0:0.0001:3;
x = 0.9*cos(2*pi*440*t);
% play it back
sound(x, 8000);
wavwrite(x, 8000, 16, example_sound.wav);_
it gives an error :
Error in ==> play123 at 6 wavwrite(x, 8000, 16, example_sound.wav);
plz help! I'm also having similar problems with image processing (i also have all the requires toolboxes)

You've posted the line, where the error appears, but not the descrption of the problem.

What is the image processing problem? Why don't you post a separate question on that, if you still have problems that enclosing the filename in quotes did not fix?

I guess, that you did not store the file name in a struct called example_sound in the field wav, but you want to use this as a file name. Then it must be defined as a string using quotes:
wavwrite(x, 8000, 16, 'example_sound.wav')
