Hello everybody! I need to simulate the Earth rotation, that is, I have a vector with the lattitudes (LatE = 0:0.5:90) and longitude as LatE = 0. I need to rotate the LatE points around the Earth, during a time t (defined). I need to save the differents points (LatE,LonE) throughout the time t. Latitudes are always the same but I don't know who to change the longitudes.
Thank you in advance

Ainoa, how about
dt = 60*60; % dt = 1 hr
t = 0:dt:24*60*60; % time vector spanning one full day
omega = 360/(24*60*60); % angular velocity of earth
LonE = omega*t
