MATLAB: Obtain maximum value of variable over multiple iterations

variable

I plan to run my code several times using a loop and want to record the maximum value of the variable 'alt.' How would I go about doing this?
 %
yr=2018;
mnth=7;
dy=0:31;
hr=0;
min=0;
sc=0;
d=datetime(yr,mnth,dy,hr,min,sc);
JD_TT=juliandate(d);
CooType='q2000';
[X,Y,Z]=moonpos(JD_TT,CooType);
[lat,lon,alt]=ecef2lla(X,Y,Z);
  end

Best Answer

E.g., you could add a variable to your looping for this:
altmax = -inf;
% your loop start
    % stuff that calculates alt
    altmax = max([alt altmax]);
% your loop end
Or you could store all of the alt values in a vector and then take the max of that vector after the loop.
