Hi, I am writing a matlab code to analyze GNSS satellite track using Rinex data. However, it comes up with error where there are too many arguments. The code is basically coming from the skyplot manual from matlab and it should be fine theoretically. How can I fix this problem in line 553? Thanks.

recPos = [0 0 0];
maskAngle = 10;
filename = "hkkt020e.24n";
data = rinexread(filename);
data.GPS(1:4,:) % Just used for understanding rine file content, basically caln ignore it
[~,satIdx] = unique(data.GPS.SatelliteID);
navmsg = data.GPS(satIdx,:);
startTime = navmsg.Time(1);
secondsPerHour = 3600;
dt = 60; % seconds
numHours = 1;
timeElapsed = 0:dt:(secondsPerHour*numHours);
t = startTime + seconds(timeElapsed);
numSats = numel(navmsg.SatelliteID);
allAz = NaN(numel(t),numSats);
allEl = allAz;
for idx = 1:numel(t)
    [satPos,~,satID] = gnssconstellation(t(idx),RINEXData=navmsg);
    [az,el,vis] = lookangles(recPos,satPos,maskAngle);
    allAz(idx,:) = az;
    allEl(idx,:) = el;
end
allEl(allEl < 0) = missing;
figure
sp = skyplot(allAz(1,:),allEl(1,:),satID,MaskElevation=maskAngle);
for idx = 1:size(allAz, 1)
    set(sp,AzimuthData=allAz(1:idx,:),ElevationData=allEl(1:idx,:));
    drawnow limitrate
end

@Yat Chi: rename your SKYPLOT file under DESKTOP/FYP_DEMO_EXPERIMENT to something that is not SKYPLOT (or the name of any other inbuilt function). For example, rename it as MYSKYPLOT.
