18 Apr 2009	saveppt2 Save Matlab figure(s) to a PowerPoint Slide Author: Jedediah Frey	Works great. One suggestion: you use print('-dmeta'...; to keep a figure's size unchanged, print('-dbitmap',['-f' ... should be used. Perhaps add this as an extra option?
01 Dec 2008	Google Earth Toolbox Various plotting/drawing functions that can be saved as KML output, and loaded in Google Earth Author: Scott L. Davis	Great work! Some issues with the demos, though. e.g.: >> demo_ge_colorbar ??? Error using ==> interp1 at 185 There should be at least two data points. Error in ==> ge_colorbar at 93 YIRed = interp1(X,YRed,fM); Error in ==> demo_ge_colorbar at 9 kmlStr = ge_colorbar(PosLong,PosLat,Z,...

23 Jan 2009	sun_position.m Sun position given observer time/location.	Falofolio	Great tool! Good job! However, I wonder, if there will be an update on this script, after reading Jeff Gullett's remarks on the code?	4
06 Jan 2009	sun_position.m Sun position given observer time/location.	Jeff Gullett	I have found a few other discrepancies in the algorithm. In the 2005 version of the document, the algorithm to compute the topocentric sun declination (eqn #39, line #825) contains the variable 'y' in the denominator, but the code presented later in the pdf document has the variable 'x' in its place. In the 2008 version of the algorithm document, this difference is resolved and the variable should be 'x' (as in the C-code, so it needs to be changed in the m-code presented on this page). Also, when computing the mean obliquity of the ecliptic (eqn #24, line #733), the documented steps have one of the terms as "-4680.93", but again, the C-code from the appendix used the term "-4680.96". Unfortunately, this discrepancy still exists in the 2008 document, so I don't know which term is correct. Using the wrong one will result in an error greater than the maximum error claimed by the algorithm designers.	Comment only
19 Nov 2008	sun_position.m Sun position given observer time/location.	EDGAR RAMOS	Congrats guy!!	5
11 Nov 2008	sun_position.m Sun position given observer time/location.	Lu Salinas	Has anyone done this same script but in excel? I've been trying it and I still have some formula wrong... I guess I'm confuse with the t ut or the radians and degrees... Would anyone want to give it a check?	Comment only
