Use atmosisa for the International Standard Atmosphere or atmoscoesa for the 1976 COESA model, passing altitude in meters. For detailed upper-atmosphere density, use atmosnrlmsise00 with latitude, longitude, date, and solar flux inputs.

gravitywgs84 takes geodetic coordinates (height in meters, latitude in degrees) and computes WGS84 gravity. gravitysphericalharmonic takes planet-centered planet-fixed [x,y,z] coordinates in meters and supports multiple planetary models like EGM2008 and GMM2B.

Call wrldmagm with height in meters, latitude and longitude in degrees, and decimal year from decyear. It returns XYZ field components in nanotesla plus horizontal intensity, declination, inclination, and total intensity.

The function expects planet-centered planet-fixed Cartesian coordinates in meters, not geodetic latitude, longitude, and altitude. Convert positions first: equator surface is [Re, 0, 0] and the pole is [0, 0, Rp].

No, atmosnonstd uses positional string arguments, not name-value pairs. Call it as atmosnonstd(height, 'Profile', extremeParam, frequency, extremeAltitude) or use the Envelope form without the extreme altitude argument.

Avoid it for coordinate frame conversions, orbital trajectory propagation, and aerodynamic coefficient calculations, which are separate workflows. Simulink environment blocks require Aerospace Blockset rather than these MATLAB functions.
