x = str2num(string)
Here string is the data string, which contains the data to
be converted into a number. The output is in double precision,
and must be typecasted to the appropriate type based on what
you need. Note that by definition, str2num is entirely
equivalent to eval(['[' string ']'],[]) with all of the
associated problems where string contains text that causes
side effects.
