on second thought, datenum makes this sorta trivial.

17 Sep 2014 day of year Date vectors converted to day of the year. Author: Joshua Carmichael

Did exactly what was advertised. An inverse function (DOY to dd:mm:yy or whatever) would be nice for symetry.

22 May 2013 Automatic Differentiation with Matlab Objects Automatically compute derivatives of functions, without using finite-difference approximations. Author: William McIlhagga

How hard would it be to have the function reshape supported? Currently it throws errors. I think because numel(a) = 1, where a is an adiff object.

I am just beginning to learn about auto differentiation and am pretty excited about something that seems to be a very powerful tool. Thanks for helping me get started.

12 Jan 2012 Calculate PSD of a signal using Welch algorithm A short function I've revised a long time ago to calculate the PSD of a signal. Author: Roni Peer

I think this function implements the Bartlett method. There is no overlap between window segments. The default Matlab pwelch overlap is 50%.
