wavwrite- wave file must be a string?

I am a newbie to matlab. I am trying to create a simple sound using matlab, just as practice for a project. I first created a vector(y) and made that a sound using:

sound(y,96000)

Now i am trying to convert this sound to .wav using

wavwrite(y,Fs,filename)

wavwrite(y,96000,f).

I created the a the function f to be the "filename".

but when i comman wavwrite(y,96000,f), it keeps giving me an error of: "wave file must be a string".

I believe f is the wavefile. I am not really sure what kind of file or function that needs and what does it mean for a wave file to be a string. I have been googling for a little while now and no luck.

If any of you could help, that would be greatly appreciated.

Thanks

I do not understand your sentence, "I created the a the function f to be the "filename"."

Example of use:

f = 'mysound.wav';
wavwrite(y,96000,f);
