[MATLAB] Fixed a problem with string length

Browse Source 
Previously the buffer length does not account for
the null terminator, which causes the string returned
from Clib to miss the last character.

The correct error code is also implemented. The
previous code will incorrectly throw an exception
when the string is a single character.
