システムトレード研究所

MATLABの復習のために、COURSERAのコースを進めている。Week4のテーマはFunctionということで、簡単な行列処理を交えた関数の作成が課題の中心。

ホームワークを提出するには、Graderと呼ばれるMATLABのファイルhw3.pをダウンロードして使用する。問題を解いて、このGraderを実行すると以下のような案内がでて、番号を選ぶことで各問題の答えをチェックすることができる。全ての問題をチェックし終えたら、"9"を選択して課題の添削を行う。添削が終わるとGraderがあるフォルダに”HW3.MOOC”というファイルが作成される。これをCourseraのコースのWebsiteにアップロードすることで、ホームワークの提出が完了する。

マイルとキロメートルの距離の変換を間違え、延々と無駄な時間を費やしたが、無事にLesson3が完了。
