Is mp3write missing from R2013B and R2013a?

Today I attempted use mp3write for the first time since downloading R2013a and R2013b and found that it is not there. Even the help said that there was no such file. I went back to R2013a and found the same thing. Can someone explain? Thanks.

I don't believe that is a MathWorks' function.

Perhaps you downloaded it from here:

If this is the case, simply add the directory it's in to your path using the pathtool.
