С помощью этого калькулятора вы сможете: получить определитель матрицы, её ранг,
возводить её в степень, найти сумму и произведение матриц, вычислить обратную
матрицу. Заполните поля для элементов матрицы и нажмите соответствующую кнопку.
* Оставляйте лишние ячейки пустыми для ввода неквадратных матриц.
* Элементы матриц - десятичные (конечные и периодические) дроби: 1/3, 3,14,
-1,3(56) или 1,2e-4; либо арифметические выражения: 2/3+3*(10-4), (1+x)/y^2,
2^0,5 (=2), 2^(1/3), 2^n, sin(phi) или cos(3,142rad).
* Используйте ↵ Ввод, Пробел, ←↑↓→, ⌫ и Delete для перемещения по ячейкам,
Ctrl⌘ Cmd+C/Ctrl⌘ Cmd+V - для копирования матриц.
* Перетаскивайте матрицы из результата (drag-and-drop), или даже из текстового
редактора.
* За теорией о матрицах и операциях над ними обращайтесь к страничке на
Википедии.
