The built-in function date returns a string containing the day, month, and year. Write a function (using the date function) that will always return the current day

whatdate.m

function [day, varargout] = whatdate

% Returns the current day and possibly also the

% current month and year

% Format of call: whatdate or whatdate()

% Returns the day; if 2 output arguments are expected,

% also the month; if 3 expected, also the year

d = date;

% always returns the day

[day, rest] = strtok(d, '-');

if nargout > 1

 % return the month also

 [month, rest] = strtok(rest, '-');

 varargout{1} = month;

end

if nargout == 3

 % return the year also

 varargout{2} = rest(2:end);

end

end
