Read the matfile documentation. It contains what you want.

Note that matfile can read from -v7 files but needs -v7.3 to write. Also, you should not expect any efficiency gains for -v7 file compared to just reading the whole variable and extracting a part of it. For such a small amount of data I would suspect that matfile for a -v7.3 file would be slower than reading the whole variable and extracting from it.
