29 Sep 2009	BASIC version of retrieving quote from google finance The function obtains quote from google finance into command line variable Author: krish reddy	Great tool! Indeed, I would also like to know if you can combine this with the datafeed toolbox. Also, it would be great if you could extend the script to get quotes of specific days/weeks.
18 Aug 2009	Display message window A simple message window similar to msgbox without button Author: Panagiotis Moulos	Function is OK. However it briefly displays a figure before displaying the message. I personally preferthe easier option to use msgbox with the OK button not visible: h=msgbox('Doing something...'); hc=get(h,'Children'); set(hc(2),'Visible','off');

30 Jun 2008	naninterp One dimensional Interpolation over NaNs.	Carlos Adrian Vargas Aguilera	Je je, nice little function, which I rader use as a script, but anyway. You should explain in the help that data should be a time series (i.e. equally spaced), you can use 'extrap' to interpolate edges, and use isnan only one time, and set the method as an optional function, use griddatan for N-dimensional array in order to make your function more interesting and is a nice test: method = 'cubic'; extrap = {'extrap'}; T = reshape(1:length(X),size(X)); inan = isnan(X); X(inan) = interp1(T(~inan),X(~inan),T(inan),method,extrap{:}); Anyway, good luck	Comment only
