Transpose the row vector to a (566272 x 1) column vector. Then you should be able to concatenate them.
Note that the first column will be the left channel, and the second column will be the right channel.
EDIT To clarify, the easiest way to do this is:
Both_Tracks = [Track_Left(:), Track_Right(:)];

From your data given above, one of them is a row and the other is a column. They should both read 1-by-566272 OR 566272-by-1. Transpose one of them and then try concatenating.

MATLAB uses the convention that columns correspond to channels.
