MATLAB has several function that allow byte-level manipulation of numeric data types (such as DOUBLE, INT32, or UINT16). These can be used to easily convert a multibyte integer into individual bytes or vice versa, check the endian-ness of a system, or convert between big and little-endian formats.
This submission consists of an m-file (ByteConversion.m) and its published HTML version (ByteConversion.html). These files demonstrate the different byte-manipulation abilities.
