Machine Learning (Andrew Ng) の宿題を提出する

Last updated at Posted at 2016-03-17

現在 Homebrew でインストールされる Octave のバージョンは 4.0.0 なのだけれども、Coursera の Machine Learning [1] の宿題を提出できない。

% octave
GNU Octave, version 4.0.0

追記: 現在は バージョン 4.0.1 以降になっており、この問題は修正されているそうなので、Octaveをアップデートするほうがよさそうです。

Course Forum [2] から ML_Octave_400_patch.zip を拾ってくる:

Are you using Octave 4.0.0? You will need to install this .

zip の中にある lib で ex1/lib を上書きすればOK.
