How can I easily get for each day in 2013 the type of day? ( Weekday, Saturday, Sunday)

Hello, I want to know if there's an easy way to get to know for each day in 2013 if it was a weekday or a Saturday or Sunday. Since the first day is in 2013 was a Tuesday, the result could be something like:

Year2013=[2 3 4 5 6 7 1 2 3 4...] or [1 1 1 1 2 3 1 1 1 1 1 2 3]...

The result can of course look different, I just want to be able to get a "number" for each day, so that I can go through the year with a loop (1:1:365) and get a number each time. Thanks a lot!

[per isakson]

Hint:

    >> day_of_year = 1;
    >> [ num, str ]= weekday( datenum( 2013, 1, 1 ) + day_of_year - 1 )
    num =
         3
    str =
    Tue

and vectorized

    >> [ num, str ] = weekday( datenum( 2013, 1, 1 ) + [1:365] - 1 );

    >> num(1:7)
    ans =
         3     4     5     6     7     1     2

With Matlab Sun is weekday 1.

    >> str(1:3,:)
    ans =
    Tue
    Wed
    Thu
    >>

And finally inspired by Sean

    [ num, str ]= weekday( datenum( 2013, 1, 1 ) : datenum( 2013, 12, 31 ) );

day = weekday(datenum('01/01/2013'):datenum('12/31/2013'))
