Convert X into string of printable characters according to RFC 2045.
The input may be a string or a matrix of integers in the range 0..255.
If want the output in the 1-row of strings format, pass the
row_vector argument as true. Otherwise the output is a 4-row
character matrix, which contains 4 encoded bytes in each column for each
3 bytes from the input.
Example:
base64encode ('Hakuna Matata', true)
⇒ SGFrdW5hIE1hdGF0YQ==
