Отчет по теме 1

Мокеев Никита, А-03-24

1 Изучение размещения компонентов графического интерфейса и главного меню среды GNU Octave

2 Настройка текущего каталога

Нажал на окно рядом с Текущая папка: и установил путь к папке ТЕМА1:

3 Настройка командного окна

Нажал на "Окно" и отметил галочками нужные окна

4 Установление путей

В главном меню нажал "Правка"+"Установить путь" и добавил пути к папкам ТЕМА1 и ТЕМА2

5 Изучение работы с системной помощью

Три способа:

"Справка"+"Документация"+"На диске" -> Function Index
команда help
для дополнительно подгружанемых пакетов "Справка"+"Пакеты Octave"

6 Создание матриц и векторов
