How can I read lat and lon data from MYD09GA hdf files?

I'm trying to read MOD09GA hdf file (e.g.,

https://e4ftl01.cr.usgs.gov/MOLA/MYD09GA.061/2002.07.05/MYD09GA.A2002186.h12v02.061.2020071185001.hdf using hdfread.

input='MYD09GA.A2002186.h12v02.061.2020071185001.hdf'
val=hdfread(input,'MODIS_Grid_500m_2D', 'Fields', 'sur_refl_b01_1');

However, I cannot find lat or lon data within hdf files. I just want to get lat and lon data from the hdf files. How can this be done?
