Линейная алгебра: от идеи к формуле from Coursera

Основная особенность нашего онлайн-курса — геометрический подход к изложению. В каждом сюжете сначала мы рассказываем идею определения, пусть иногда и нестрого, а уже затем вводим формальное определение. В частности, линейные операторы, собственные векторы и числа появляются до матриц и определителей. Матрицы мы излагаем как способ записи линейного оператора. В силу этой особенности курс может быть интересен и тем, кто уже освоил стандартный вводный курс линейной алгебры. Основные темы курса: векторные пространства, линейные операторы и их свойства, квадратичные формы, матричные разложения, метод главных компонент. Иногда для...
