It would help if you told us which line the problem was occurring on.
In your code, what do you expect to have happen if the file is not at least 19807 long ?
It is not clear to me that your code is taking into account the possibility that the file is multiple channels (stereo) ?

It happens when you do things like this
>> a=1:7; a(8)
Index exceeds matrix dimensions.
Use DBSTOP to trap the error.

You unconditionally try to access
modres(UvStartIdx(i):UvEndIdx(i))
for all "i" values possible for those two arrays. The maximum UvEndIdx value is 19807 so you are attempting to access up to index 19807 of modres(). However, your modres is not that long.
We have no information about your EpochProsodyModResidualModFn function, so we cannot tell you why your modres is coming out shorter than you expect.
