Вызов списка демонстрационных примеров


Одним из самых эффективных методов знакомства со сложными математическими

системами является ознакомление со встроенными примерами их применения.

Система MATLAB содержит многие сотни таких примеров — практически по

примеру на каждый оператор или функцию. Наиболее поучительные примеры

можно найти в разделе demos, исполнив команду

» help demos

Ниже представлен выводимый этой командой список примеров:
