How to unzip .bz2 file in Matlab?

How can I unzip the following .bz2 automatically in Matlab to reveal the grib file inside?

clear all
close all

fullURL1 = sprintf('https://opendata.dwd.de/weather/nwp/icon/grib/00/clch/icon_global_icosahedral_single-level_2020122000_000_CLCH.grib2.bz2');
fullURL = [fullURL1];
filename = 'highcloudcover.grb2.bz2';
urlwrite(fullURL,filename);

Thanks

But how can I implement this in Matlab software?

system() .

You can construct the command.

cmd = sprintf("bzip2 -dk '%s'", filename);
system(cmd)

Hi, I solved it with this:

filename = 'cloudcover.grib2.bz2';
urlwrite(fullURL,filename);
cmd = sprintf("bzip2 -dk '%s'", filename);
system(cmd);
filename = 'cloudcover.grib2';

Yes, you need to install bzip2; https://sourceforge.net/projects/bzip2/
