Lat long Conversion from geodetic to ECEF

I have a problem. I want to convert lattitude and longitude from geodetic coordinates(given in degrees as 33.7660° N, 72.3609° E) to ECEF. There is a function for this as "lla2ecef' but it only do it for one position and I want to do it for like 4 coordinates (lat,long) and I have no clue. Any help would be appreciated.

You can input your 4 coordinates in lla2ecef like

p = lla2ecef([0 45 1000; 45 90 2000], 'WGS84');

Here, it is 2 coordinates(lat, lon, and h) are used. You can find more details at Determine ECEF Coordinates at Multiple Latitudes, Longitudes, and Altitudes section of https://in.mathworks.com/help/aerotbx/ug/lla2ecef.html

You can also look into geodetic function.

Hello @Amritesh..

I am using the above function as given but it gives me error while all the relevant syntax is correct. kindly review it.

[x(k),y(k),z(k)] = lla2ecef(latR_DME(k) ,lonR_DME(k), alt);
