This function calculates the decimal day of the year of the input vector of dates. The dates must be in MATLAB serial date format.

For example, for datestr(now), MATLAB produces: "18-Jan-2008 14:33:27". The output of this function, called "date2doy" yields-
date2doy(now): "18.60662".

There are two outputs, the decimal date (can be a vector), and the fraction of the year completed by that date. From the example above, the fraction of the year is: "0.0481"

This function is very fast, and is ideal for embedding in larger applications that call date2doy many times.

In response to James' review, I've heavily modified this function and taken all of his suggestions. Also, the calculation, while simple, is not as trivial as James mentions.
