24 Feb 2014 SKY MAP (GUI) A MATLAB software that shows the position and relative brightness of stars in the sky Author: Daniel Okoh

Hello Cody and Iftikhar, a function equivalent of SKY MAP is now available. You can now use this function as part of your program. How to do this is explained on the SKY MAP (function) website:

http://www.mathworks.com/matlabcentral/fileexchange/45673-sky-map-function

Let me know if you have any problems.

hi Cody, at the moment SkyMap is written with it's own GUI, and you will not be able to embed it directly into your program without some modifications. I could however assist you get it in that format if you don't need it so urgently as I'm currently busy with another work. Let me know if it won't be late in 2 or 3 weeks.

hi Gene, it's possible you don't have the Mapping Toolbox on your Matlab. 'linecirc' is a Matlab function on the Mapping Toolbox.

The Mapping Toolbox is likely missing on your Matlab installation.

22 Oct 2014 Day of year A function that computes the day number (or day of year) for any given date, Enhanced. Author: Daniel Okoh Chad Greene

To make this function work for arrays, change the n= line to

n = datenum([d(:,1:3), zeros(size(d,1),3)]) - datenum([d(:,1), ones(size(d,1),1),zeros(size(d,1), 4)]);

Hello Daniel,

Thank you for this code. I downloaded the function and changed a few lines to let me calculate the azimuth and elevation angles for different stars. I compared the results with C2A program and got good agreement (to 0.01 deg). Do you have any idea how accurate the star angles are supposed to be? Thanks again

23 May 2014 Month and Day of month to Day of year (mmdd2ddd.m) Converts month and day of a month to corresponding day of the year Author: Daniel Okoh Jan Simon

The Financial Toolbox is required for this function.

23 May 2014 Day of year to Month, Day of Month (ddd2mmdd.m) Converts day of a year to corresponding month and day of the month Author: Daniel Okoh Jan Simon

A function without a documentation is not useful. A help section is obligatory.

A simpler version, which does not need the Financial Toolbox:

function [mm,dd] = ddd2mmdd(year, ddd)
v = datevec(datenum(year, 1, ddd));
mm = v(2); dd = v(3);
