I am trying too run a script that involves this function:
rho = nrlmsise00(altitude, year, month, day, hour, minute, second);
Every time I try to fix it, I get the same errors. If I reduce the input arguments, I get the too many input arguments error until I reduce it to nothing (then I get the too many output arguments error). I don't have the Aerospace toolbox, so I downloaded the nrlmsise00 function off of this site, and I don't know if it has been added to the path, but I tried every way to add it. What are your thoughts? Please help, thank you.

@Torsten Yes, that is the one, but should I just put in the function by itself in my orbit propagation code? I'm trying to get a density out of it.

Ran in:
The results for the defined testcase seem to coincide with what is stated in the Documentation (see below).
You will have to adapt the function nrlmsise00 according to your needs (which means you have to understand which data you have to supply (input structure) and which data you can get out of the function (output structure)) .
nrlmsise00()

The nrlmsiese00 function at https://www.mathworks.com/matlabcentral/fileexchange/56253-nrlmsise-00-atmosphere-model does not accept any inputs and does not produce any outputs.
Instead of inputs, you need to adjust the values in the lines
flags = struct('switches',zeros(24,1),'sw',zeros(24,1),'swc',zeros(24,1));
ap_a = struct('a',zeros(7,1));
input = struct('year',0,'doy',0,'sec',0,'alt',0,'g_lat',0,'g_long',0,'lst',0,'f107A',0,'f107',0,'ap',0,'ap_a',ap_a);
