It only operates on one vector at a time, and returns a matrix of column vectors (regardless of the original vector orientation), so for a stereo signal, it will be necessary to do this for each column (channel) separately.

The ‘some small files’ requirement is a bit ambiguous.
Choose an integral divisor of the number of rows in the file, then choose that number to be the second argument to reshape (the first is the matrix itself), then go for it!
wavmatrix = [1:20; 21:40]';
newmatrix = reshape(wavmatrix, 10, [])
The first and second columns are the left channel, and the third and fourth columns are the right channel.
I leave the rest to you!
