%
% Usage
%
% Converts a string to a number. The general syntax for its use
% is
%
% 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.
function y = str2num(x)
if (~isstr(x))
y = [];
return;
end
try
y = eval(['[',x,']'],'[]');
catch
y = [];
end
