Hello, is it possible to add a direct link for lecture notes below this video. I tried using the coupon but it showed “the coupon code does not exist” ! Thank you.

Hello, I couldn’t get the signal package installed. the following erros message kept showing up, looks related to “medfilt1.cc” file in \src folder. [Note, my system is Windows10]. Octave 4.4.1 installed].

Please let me know how this can be resolved, tks a lot.

>> pkg install signal-1.4.0.tar.gz
medfilt1.cc: In member function ‘void sorted_window::init(const double*, octave_idx_type, octave_idx_type, oct
ave_idx_type)’:
medfilt1.cc:91:7: error: ‘bzero’ was not declared in this scope
bzero (buf, zeros * sizeof (double));
^~~~~
medfilt1.cc:91:7: note: suggested alternative: ‘zeros’
bzero (buf, zeros * sizeof (double));
^~~~~
