Remark:
To run the Octave (or Matlab) codes on your laptops
1. you have to install the Octave
2. being linked to internet and having opened the Octave platform, you have to install the statistics package
>>pkg install -forge statistics
next the statistics package have to be loaded into the Octave platform
>>pkg load statistics
4. now the Octave platform is ready to run our Octave codes.
