# 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
